B1A4 (Korean: 비원에이포; pronounced Bee-won-ay-fo) is a South Korean boy band formed by WM Entertainment in 2011, with the group name signifying "Be the one, all for one."[1] Originally a five-member ensemble consisting of CNU, Jinyoung, Baro, Sandeul, and Gongchan, the group debuted on April 23, 2011, by performing the single "O.K" from their debut EP Let's Fly on MBC's Show! Music Core.[2] In June 2018, following the expiration of their contracts, Jinyoung and Baro elected not to renew with the agency and ceased group promotions, leaving CNU, Sandeul, and Gongchan to continue as B1A4 after renewing their contracts.[3][2]The group received early recognition for their debut, securing awards such as Hot Debut Star at the 2011 SBSMTV Best of the Best and Rookie of the Year at Japan's Tower Records K-Pop Lovers! Awards.[4][5] Over the years, B1A4 released multiple albums and singles, distinguishing themselves in K-pop by emphasizing live instrumentation and vocal harmonies, as highlighted in tracks like "Sweet Girl."[6] Jinyoung's role as a primary songwriter shaped much of their discography prior to his exit, contributing to their reputation for self-produced content. Despite member changes and shifts in the K-pop landscape, the remaining trio has persisted with group activities, including scheduled performances as of 2024, even as Gongchan concluded his individual contract with WM Entertainment while retaining agency support for B1A4 endeavors.[7]
History
Pre-debut and formation (2010)
B1A4 was assembled in 2010 by WM Entertainment, a South Korean agency established in 2008, as its first boy group project comprising five members selected from trainees.[8] The lineup included Jinyoung as leader and primary producer, alongside CNU, Sandeul, Baro, and maknae Gongchan, who had been recruited via scouting and auditions with training durations ranging from one to two years prior.[9] During this pre-debut phase, the members concentrated on honing vocal techniques, choreography, and performance skills under rigorous schedules typical of K-pop trainee systems, setting the stage for their 2011 launch.[8] No public reveals occurred in 2010, with preparations remaining internal to build group cohesion and repertoire.[9]
2011–2012: Debut, early releases, and Japan entry
B1A4 released their debut mini-album Let's Fly on April 21, 2011, under WM Entertainment, featuring the lead single "O.K", a dance-pop track composed by Seo Young-bae with lyrics by Geul Gongjang.[10][11] The group, consisting of vocalists CNU, Sandeul, and Jinyoung, rappers Baro and Gongchan, officially debuted two days later on April 23, 2011, performing "O.K" on MBC's Show! Music Core, marking their entry into the K-pop scene after pre-debut promotions via a webtoon series.[12][9] The album included self-composed elements, such as a track written and composed by leader Jinyoung, which drew attention for the rookies' creative involvement.[13]Following their debut, B1A4 issued their second mini-album it B1A4 on September 16, 2011, led by the single "Beautiful Target", which emphasized their upbeat, electronic-infused pop style and gained traction through music show performances.[14][11] In early 2012, they released the digital single "This Time Is Over" on March 5, followed by their first full-length studio album Ignition on March 14, promoting the title track "Baby I'm Sorry" and showcasing a mix of R&B-influenced dance tracks and ballads.[9][15] Later that year, the mini-album In the Wind arrived in May, with lead single "Tried to Walk" highlighting emotional vocals and continued their momentum through domestic promotions.[16]B1A4 expanded internationally by entering the Japanese market in 2012 under Pony Canyon, following an announcement in October 2011 of a planned debut.[17] They held a debut showcase in Japan on December 16, 2011, ahead of releasing the Japanese version of "Beautiful Target" as their first single on June 27, 2012, which charted at number four on the Oricon weekly singles chart with over 32,000 copies sold in its debut week.[18][19] This was followed by their debut Japanese studio album 1 on October 24, 2012, in multiple editions, solidifying their early overseas presence.[9]
2013–2014: Commercial breakthroughs and global expansion
In January 2013, B1A4 earned international acclaim by winning Best New Artist (Asia) and being named among the Best 3 New Artists (Asia) at the Japan Gold Disc Awards, as announced by the Recording Industry Association of Japan on January 7.[20][21] Later that year, on May 6, the group released their fourth mini-album What's Happening?, with the title track securing their first music show victory on MBC's Show! Music Core on May 18.[9] The album achieved commercial success, selling 101,988 copies and ranking 21st on South Korea's Gaon Album Chart yearly tally for 2013.[22]Building on this momentum, B1A4 expanded their Japanese presence with tours such as BABA B1A4 in Japan and the Limited Show [Amazing Store] Zepp Tour in 2013, followed by the arena-scale Listen to the B1A4 tour in 2014.[23] In Korea, they released their second studio albumWho Am I on January 13, 2014, led by the single "Lonely," and their fifth mini-albumSolo Day on July 14, 2014.[24][25]The period marked B1A4's global push, including a performance at KCON 2014 in Los Angeles on August 9.[26] They launched their debut world tour, 2014 B1A4 Road Trip, in late August, spanning Taiwan, China, the Philippines, Australia, Japan, and the United States, with U.S. dates in New York on October 3, Chicago on October 5, and Dallas on October 8.[27][28]
2015–2018: Peak activities, internal shifts, and member agency departures
In 2015, B1A4 embarked on their "B1A4 ADVENTURE" world tour, performing in multiple countries including the United States, Europe (such as Helsinki, Berlin, and Madrid in December), Taiwan, China, and Australia, marking an expansion of their international fanbase following prior commercial successes.[29][30] The group maintained active promotions with Japanese releases, including the single "Feel Good" in March, underscoring their dual-market strategy in Korea and Japan.The period saw continued musical output, with the release of their third mini-album 3 on January 7, 2016, followed by the second studio album Good Timing on November 28, 2016, both featuring self-produced tracks primarily composed by member Jinyoung, who handled lyrics, composition, and arrangement for the majority of title tracks and B-sides since 2012.[31][32] This self-production emphasized the group's artistic evolution toward more mature, emotional pop-rock sounds, with Jinyoung's contributions extending to external projects, reflecting internal creative autonomy amid WM Entertainment's management.[33]Subsequent releases included the fourth mini-album 4 on November 6, 2017, and the fifth mini-album 5 on June 26, 2018, alongside a Japan best album compiling hits from 2012–2018 on September 26, 2018; these efforts sustained visibility despite shifting domestic K-pop landscapes.[31][34] Internally, tensions arose over contract renewals as the group's seven-year terms neared expiration on June 30, 2018, with discussions focusing on compensation, creative direction, and individual career paths.[35]On June 30, 2018, members Jinyoung and Baro declined to renew their contracts with WM Entertainment after extended negotiations, effectively departing the agency while CNU, Sandeul, and Gongchan renewed, leading to uncertainty about group continuity but no immediate disbandment.[36][2][37]WM Entertainment confirmed the terminations, noting the duo's contributions since 2011, and stated that future promotions would involve the remaining members.[3] This shift reduced the group to a trio under WM, with Jinyoung and Baro pursuing solo endeavors elsewhere, highlighting agency-member agency disputes common in K-pop contract cycles.[38]
2019–2023: Military enlistments, limited releases, and group hiatus
CNU enlisted for mandatory military service on January 22, 2019, as an active duty soldier, reducing B1A4's promotional activities to the remaining duo of Sandeul and Gongchan.[39][40] CNU completed his service and was discharged on August 28, 2020.[12] Following his return, the trio released their fourth studio album Origine on October 19, 2020, featuring the lead single "Like a Movie," marking their first full-length release as a three-member unit.[41]In 2021, B1A4 issued limited digital singles to commemorate their 10th anniversary, including "10 Times" on April 23 and "Enormous Words" (also known as "Adore You" in some translations) on November 6.[15]Sandeul enlisted for military service as a public service worker on November 11, 2021, after completing basic training. This enlistment, combined with prior member departures and CNU's earlier service, prompted a group hiatus, with members focusing on individual endeavors; Gongchan was exempted from service in March 2023 due to health issues stemming from a 2012 kidney removal surgery.[42][43]CNU renewed his contract with WM Entertainment on March 13, 2023.[44]Sandeul was discharged on August 10, 2023, concluding the period of sequential enlistments that had limited group promotions since 2019. During the hiatus, no further group releases occurred until 2024, as the members prioritized solo acting, variety appearances, and personal projects amid mandatory service obligations.[45]
2024–2025: Final promotional album, post-military transitions, and anniversary events
In January 2024, B1A4 released their eighth mini album Connect on January 8, featuring the lead single "Rewind," which was co-written and composed by members CNU, Sandeul, and Gongchan.[46][47] This marked the trio's first group comeback since 2021, following the completion of mandatory military service for all current members: Sandeul discharged on April 9, 2021, after enlisting on June 20, 2019; Gongchan discharged on October 26, 2021, after enlisting on January 22, 2020; and CNU discharged on August 28, 2020, after enlisting earlier that year.[12][48] The album's release emphasized themes of reconnection and reflection on their career trajectory amid transitions, including the departure of former members Jinyoung and Baro from WM Entertainment in prior years.[45]Promotions for Connect included performances on major music programs such as Music Bank, where the group appeared in coordinated winter attire to engage fans during the winter broadcast season.[49] Post-discharge, CNU renewed his contract with WM Entertainment in March 2023, signaling continued group commitment, while Sandeul and Gongchan focused on individual acting and variety pursuits alongside band activities.[50]To commemorate their 13th anniversary since debuting on April 23, 2011, B1A4 held a series of fan concerts titled "13ANA=DAY" on April 20 and 21, 2024, at Yonsei University's Centennial Hall, with three sessions that sold out rapidly.[51][52] The events featured setlists spanning their discography, fan interactions, and announcements of ongoing global outreach. Extending anniversary celebrations, they performed a dedicated fan concert in Taiwan on November 10, 2024, at National Taiwan University, marking their return to the region after seven years.[53]Into 2025, the group sustained momentum with a joint concert alongside labelmates ONF titled "FLY WITH LIGHT" in Taipei on June 21, followed by solo fan-cons such as "Singularity: Our Time" in Hong Kong on July 11 at MacPherson Stadium and additional dates in Japan.[54][55] For their 14th anniversary in June 2025, B1A4 participated in a commemorative photoshoot and outlined plans for expanded international fan engagements, reflecting stability in their reduced lineup.[55]
Members
Current members and roles
B1A4 currently consists of three members: CNU, Sandeul, and Gongchan, who remain under WM Entertainment after Jinyoung and Baro declined contract renewals on June 30, 2018.[12][56]CNU (stage name of Shin Dong-woo, born June 16, 1991) acts as the group's leader, lead rapper, and lead vocalist; he stands at 182 cm, the tallest member, and has contributed to songwriting and production in past releases.[12][56]Sandeul (stage name of Lee Jung-hwan, born March 20, 1992) serves as the main vocalist, recognized for his powerful and versatile singing range, including a solo mini-album Oxygen released on May 3, 2016.[12][56]Gongchan (stage name of Gong Chan-sik, born August 14, 1993) functions as lead dancer, vocalist, visual, and maknae, often highlighted for his facial features and dance contributions in group performances.[12][56]
Former members and departures
On June 30, 2018, B1A4 members Jinyoung (Jung Jin-young) and Baro (Cha Sun-woo) departed from WM Entertainment after choosing not to renew their contracts upon expiration.[2][36] The agency confirmed that CNU, Sandeul, and Gongchan had renewed their contracts and would proceed with group promotions under the B1A4 name, emphasizing continuity despite the changes.[2]Although initial statements left room for potential joint activities, WM Entertainment officially announced on November 16, 2018, that Jinyoung and Baro would cease promoting as part of B1A4, marking their full exit from the group to pursue independent careers in acting and other solo endeavors. Jinyoung, who had served as the group's leader and primary producer, transitioned to focus on songwriting, composing, and roles in dramas such as Moonlight Drawn by Clouds prior to his departure. Baro, known for his rapping and deep vocal tone, similarly shifted toward acting projects including films and television series. No conflicts or disputes were publicly cited as factors in the departures, with the agency expressing gratitude for their contributions during the group's first seven years.
Artistry
Musical style and evolution
B1A4's music primarily encompasses dance-pop and electropop, with frequent incorporations of ballad elements and vocal harmonies that highlight the group's strengths in melody-driven tracks.[13] Debuting in 2011 with the upbeat single "O.K" from their EP Let's Fly, the group initially favored lively, playful compositions characterized by energetic rhythms and aegyo-infused concepts, as seen in early releases like "Baby Good Night," which emphasized fun, party-oriented sounds.[57] This phase reflected a youthful, accessible K-pop formula, with leader Jinyoung contributing compositions from the outset to infuse personal touches.[33]Over time, B1A4 shifted toward greater maturity and genre experimentation, particularly from 2012 onward. The 2012 single "In the Wind" marked an early pivot to more sophisticated arrangements, departing from their prior childish aegyo image toward emotional depth in lyrics and production.[58] By 2013–2014, albums like Who Am I introduced synth-heavy ballads such as "Lonely," blending 1980s synthesizer influences with Southern hip-hop beats, largely self-produced by Jinyoung (who handled the title track and seven others) and CNU (contributing two compositions).[59][60] This era showcased their growing emphasis on member-led production, with Jinyoung and CNU co-writing and arranging multiple tracks across releases, enabling diverse fusions of pop, R&B, and rock elements.[33][61]In later years, particularly 2017 and beyond, B1A4 further diversified, moving away from uniformly upbeat themes. The 2017 track "Rollin'" represented a stylistic evolution, incorporating varied emotional tones rather than relying solely on "happy" motifs, as noted by members reflecting on their maturation.[62] Releases like "Like a Movie" (2020) leaned into slow-tempo ballad pop with mature, cinematic arrangements that prioritized vocal layering and intricate production.[63] Their self-production remained a hallmark, with full albums such as Origine (2020) demonstrating sustained control over composition amid group challenges like enlistments.[33] This progression underscores B1A4's adaptation from rookie exuberance to a more introspective, versatile sound, distinguishing them through consistent member involvement in creative processes.[64]
Performance elements and member contributions
B1A4's performances emphasize live vocal stability and energetic execution over highly synchronized or acrobatic choreography, enabling the group to maintain strong singing during concerts with minimal reliance on lip-syncing.[65][66] Reviews of their live shows highlight solid vocal delivery across sets, with clean dance movements that support rather than overshadow the music, contributing to a mature stage presence focused on audience connection rather than visual spectacle.[65] This approach allowed for high-energy openings and sustained performance quality in tours, distinguishing B1A4 from dance-centric contemporaries.[61]Sandeul, as the main vocalist, provides the group's vocal backbone with powerful technique, high-range belts, and emotional depth, often leading choruses and ad-libs in live settings to showcase raw singing ability.[67] CNU contributes stable harmonies, sub-rap verses, and versatile support vocals, enhancing group dynamics through consistent tone and performance reliability during extended sets.[65]Gongchan handles supporting vocals with a softer, delicate timbre that contrasts the leads, while leading dance elements and providing visual focal points through expressive movements and fan interaction.[49]Former members Jinyoung and Baro added lead vocal layers and deep-toned rap sections, respectively, bolstering early performances with compositional input and rhythmic drive that integrated into the group's vocal-leaning style.[12] In the current trio configuration post-2018, performances rely more heavily on vocal interplay among CNU, Sandeul, and Gongchan, adapting choreography to smaller formations while preserving emphasis on live singing prowess evident in recent releases and anniversary events.[65]

Korean discography
B1A4's Korean discography comprises four studio albums and seven extended plays, spanning their active years from debut to recent comebacks. The group emphasized mini-albums (extended plays) early on, with title tracks driving promotions on music shows, while full-length albums arrived later and included self-produced elements by members like Jinyoung. Releases tapered during military enlistments from 2018, resuming with limited output by CNU, Sandeul, and Gongchan post-2020.[4][15]

Public image
Fandom dynamics and media presence
B1A4's official fandom is named BANA, a term coined by leader Jinyoung on July 31, 2011, combining "BA" for the group and "NA" for fans to imply mutual affection, as in "we have fallen for each other."[120] BANA members have shown sustained loyalty, particularly following the 2018 non-renewal of contracts by Jinyoung and Baro with WM Entertainment, which reduced group promotions but did not erode core fan support.[121] This resilience is evident in ongoing international fan clubs and community platforms like Weverse, where fans engage with updates and content.[122][123]Fan dynamics emphasize organized support through official memberships, which provide kits and priority access to events, such as the 8th BANA membership kit released in 2025.[124] Activities include participation in fan concerts and voting campaigns for music programs during active periods, fostering a sense of community despite the group's shift toward individual endeavors announced on January 22, 2024.[125] Fans have been described in online discussions as particularly sweet and dedicated, contributing to positive perceptions of B1A4's supporter base compared to more intense K-pop fandoms.[126]In terms of media presence, B1A4 frequently appeared on South Korean music programs early in their career, including performances on Mnet's M! Countdown, such as "Yesterday & What's Happening?" on May 9, 2013.[127]Variety show features and international events like KCON 2014 further amplified their visibility.[128] Post-2018, coverage shifted toward Japanese promotions and fan meetings, with recent attention on anniversary fan-cons, including "Singularity: Our Time" events in Hong Kong on a date in 2025 and Tokyo on July 21, 2025.[129][110] This sustained but niche media footprint reflects the group's transition to selective, fan-focused engagements rather than mainstream chart dominance.[125]
Commercial reception and sales data
B1A4's commercial reception in South Korea was moderate, with physical album sales peaking during their mid-2010s releases before declining in later years amid a shifting K-pop market dominated by higher-volume groups. Cumulative Korean album sales exceeded 848,000 units as of early 2021, driven primarily by domestic physical chart performance on platforms like Gaon (now Circle) and Hanteo. Their best-selling release, the second studio album Who Am I (January 13, 2014), achieved 127,810 total sales, including 67,206 copies in its first week on Hanteo and 99,675 in the first month on Circle.[68][130] Earlier mini-albums like What's Happening? (May 7, 2013) sold 106,779 copies overall, reflecting strong initial fan demand.[68]Later releases showed reduced figures, indicative of broader industry trends toward digital streaming and exports; for instance, the fourth studio album Origine (October 19, 2020) sold 49,182 copies total, and the eighth mini-album Connect (January 8, 2024) reached 35,653 copies.[68] No Korean albums received certifications from the Korea Music Content Industry Association, as sales volumes fell short of thresholds like 100,000 for gold status on full-length releases.

In Japan, B1A4 found greater chart traction through Pony Canyon releases, particularly singles that leveraged their concert draw and media appearances. The single "Shiroi Kiseki" (January 21, 2015) debuted at number one on the Oricon Daily Singles Chart and sold 69,748 copies total, marking their strongest single performance.[68][75] Other hits included "Ige Museun Iriya" (August 28, 2013) with 49,789 copies and "Solo Day -Japanese ver.-" (September 10, 2014) with 48,490 copies, often peaking in the top five weekly.[68] Japanese albums performed more modestly, with the debut 1 (October 24, 2012) selling 24,128 copies total despite a strong first-week Oricon debut. Overall Japanese physical sales contributed significantly to their international revenue, though exact aggregates remain unconsolidated in official reports.[68]
Controversies
2015 Malaysia fan meeting incident
On January 10, 2015, B1A4 held a fan meeting titled "B1A4 Acer Special" at KL Live in Kuala Lumpur, Malaysia, organized by TGM Events.[131] During the event's meet-and-greet segment, several female fans, including Muslim attendees wearing hijabs, were invited onstage where members of the group embraced them and one member, Gongchan, kissed a fan on the forehead.[132] Fan-recorded videos of these interactions circulated online, often under sensational titles such as "Malay Girls Molested On Stage By K-Pop Band B1A4," amplifying public outrage in conservative segments of Malaysian society.[133][134]The interactions sparked controversy for contravening Islamic guidelines on physical contact between unrelated men and women, interpreted by authorities as potential violations of khalwat (close proximity) or public indecency under Malaysia's Sharia laws applicable to Muslims.[135] The Federal Territories Islamic Religious Department (JAWI) summoned at least four involved Muslim fans for questioning, issuing notices that carried penalties of fines up to RM 5,000 (about USD 1,500) or up to three years' imprisonment.[133]Muslim NGOs, including Pertubuhan Ikram Malaysia, condemned the event organizers for failing to enforce cultural and religious sensitivities, such as segregating audiences or prohibiting such contact, and demanded stricter oversight for future K-pop events.[136] B1A4, unaware of the specific prohibitions due to cultural differences in Korean fan interactions, faced limited direct backlash, with some international fans and a U.S.-based defender launching online campaigns portraying the hugs as innocent gestures.[137]In April 2015, the Malaysian Tourism and Culture Ministry blacklisted TGM Events for violating event guidelines, citing inadequate risk assessment and failure to brief performers on local norms.[131][138]Arrest warrants for the fans were ultimately withdrawn after they cooperated with investigations and public pressure highlighted the disproportionate response to what proponents described as standard, non-sexual K-popfan service.[139] The incident underscored tensions between global K-popfandom practices and Malaysia's conservative Islamic framework, leading to calls for enhanced pre-event cultural training but no formal sanctions against B1A4 itself.[132]
2016 SNL Korea sexual harassment allegations
In October 2016, members of the South Korean boy band B1A4 faced allegations of sexual harassment during their appearance on the variety show SNL Korea. On October 22, female production staff and cast members, including comedian Lee Se-young, reportedly groped the performers' genital areas as part of a purported "initiation ceremony" or group cheer ritual conducted backstage before taping.[140][141] Video footage of the incident, which surfaced online shortly after, showed staff members approaching the idols and performing the acts without apparent consent, prompting widespread public outrage among fans and netizens who labeled it as sexual assault.[142][143]Lee Se-young issued a personal apology via Instagram on November 28, admitting to participating in the groping and expressing regret, while claiming it was intended as playful camaraderie but acknowledging the harm caused.[141] The SNL Korea production team followed with multiple apologies, including a second statement on November 29 confirming that such initiation rituals had occurred since the show's inception in 2011, though explicit sexual harassment elements were described as emerging only in the prior year; they pledged to discontinue the practice and implement reforms.[144] B1A4's agency, WM Entertainment, responded on November 28 by stating the members had not reported discomfort at the time but supported the investigation into the claims.[145]The controversy escalated when B1A4 fans filed criminal complaints with the Seoul Metropolitan Police Agency, leading to a formal investigation announced on December 1; police planned to question the B1A4 members as victims and review evidence, including the video.[146][147] Lee Se-young's case was specifically forwarded to the Mapo Police Department for scrutiny under South Korea's sexual violence laws, and she declined the 24th Korean Culture and Entertainment Award on November 30 amid the backlash.[148][149] Critics highlighted a perceived double standard in Korean society regarding female-on-male harassment, with commentators noting leniency compared to male perpetrators, while revelations emerged of similar unaddressed incidents involving groups like INFINITE on the show.[140][150] The episode intensified scrutiny of SNL Korea's workplace culture, though no criminal charges were publicly confirmed against the involved parties in subsequent reports.[151]
Chart manipulation accusations and other criticisms
In January 2014, following the release of B1A4's second studio album Who Am I on January 13, B1A4 and their agency WM Entertainment faced netizen accusations of sajaegi—the deliberate manipulation of music chart positions through bulk purchases or other artificial inflation. Critics pointed to anomalous sales data, including reports of the album selling out across major retailers in roughly 3.5 hours and a sharp increase in Gaon Chart rankings from previous releases, which they argued deviated from organic patterns.[152][153]WM Entertainment issued a denial, stating that no sajaegi activities occurred and attributing the sales surge to genuine fan demand built from prior promotions. Analysts suggested the claims stemmed from inter-fandom rivalries rather than verifiable irregularities, as B1A4's pre-album physical sales had shown steady growth without prior red flags. No official probe by authorities or chart operators ensued, with Gaon and Hanteo officials indicating that their real-time tracking and anti-manipulation protocols rendered large-scale sajaegi implausible in this instance.[152]Other criticisms of B1A4 have been sporadic and less substantiated, often tied to individual member conduct during promotions. For instance, in 2012, tensions arose between B1A4's fandom (BANA) and Dal Shabet's supporters over online disputes, prompting joint statements from WM Entertainment and the rival agency urging fans to cease hostilities. Additionally, member Baro drew minor backlash in 2016 for perceived rudeness toward staff during a variety show appearance on Please Take Care of My Refrigerator, though the agency framed it as a misunderstanding and no formal repercussions followed.[154][155]
Philanthropy
Charitable contributions and campaigns
B1A4 has engaged in several philanthropic initiatives, often collaborating with fans and organizations to support children, the elderly, and those facing economic hardship. In August 2012, the group facilitated the donation of 140 kilograms of rice garlands, originally sent by fans, to the Seoul SOS Youth Camp in Yangcheon District, benefiting approximately 1,300 underprivileged children.[156][157]Following their first solo concert "BABA B1A4" in December 2012, B1A4 coordinated the redistribution of fan-donated items—including nearly 2 tons of rice, 2,356 coal briquettes for winter heating, 300 kilograms of animal feed, and 10 mango trees—to various welfare organizations aiding the needy and energy-poor households.[157]In July 2013, during preparations for their concert series, B1A4 partnered with CJ Group's "Donor's Camp" foundation to collect school supplies from approximately 3,000 attendees, amassing five tons of new and unused items donated under the group's name to support the education of children in financial need.[158]The group has also participated in direct beneficiary events, such as a May 2013 collaboration with Make-A-Wish Korea, where they fulfilled the wish of 12-year-old Shin Heewon, who has muscular dystrophy, by granting him a personal meeting and gifting signed merchandise while encouraging his continued treatment.In December 2014, B1A4 members took part in a coal distribution charity event organized to deliver heating fuel to low-income families during winter, emphasizing community support amid cold weather challenges.[159]
