Sungho

Park Sungho, known mononymously as Sungho, is a South Korean singer and the leader and main vocalist of the six-member boy group BoyNextDoor, formed by KOZ Entertainment under HYBE Corporation. He debuted with the group in May 2023 and has since become recognized for his powerful vocal tone and charismatic stage presence. As the leader, Sungho guides the group through its youthful, energetic concept, connecting with fans through music that captures the honest feelings of youth. BoyNextDoor has built a dedicated fanbase both in South Korea and internationally, with multiple EPs and singles to their name. Sungho continues to grow as an artist, focusing on group activities and live performances.[edit]

Sungho was born and raised in Wonju, a city in Gangwon Province. He developed an early passion for music and performing, which led him to audition for KOZ Entertainment, the label founded by rapper Zico. After passing the audition, he became a trainee, undergoing rigorous training in vocals, dance, and stage presence. His training period was kept largely private, but it prepared him to take on the role of leader for the group that would become BoyNextDoor. Before his debut, Sungho honed his skills and built the foundation for his career as a K-pop idol.[edit]

Sungho debuted as the leader of BoyNextDoor on May 30, 2023, with the single album Who!. The group quickly followed up with their first EP Why.. in September 2023, featuring the title track “But Sometimes.” Later that year, they released the single album What Else with the track “Earth, Wind & Fire.” In April 2024, BoyNextDoor dropped their first studio album 19.99, marking a major milestone. The group continued to release music, including the 2025 single “If I Say, I Love You.” As of 2026, Sungho is actively promoting with BoyNextDoor, performing at festivals and award shows, and engaging with fans through variety content and fan meetings.[edit]

Sungho is known for his youthful, energetic image that aligns with BoyNextDoor's “boy next door” concept. He often sports trendy, casual fashion and styled hair. Media portrayals highlight his leadership and vocal ability, focusing on his stage presence. The group's fandom, called ONEID, engages in streaming parties, voting campaigns, and fan art. Sungho's social media presence is managed through the group's official accounts, which use a friendly, engaging tone to interact with fans via behind-the-scenes content and live streams.[edit]

Since BoyNextDoor's debut in May 2023, the group has cultivated a vibrant, digitally-native community that mirrors their youthful energy. As the main vocalist and leader, Sungho anchors this dynamic, often engaging with fans through Weverse where his specific emoji, a black square, serves as a unique identifier for interaction. While the group is frequently praised for its "boy next door" charm and Gen Z swag, the fanbase remains largely defined by its collective support rather than a singular, documented official name for Sungho alone. This audience is highly active in streaming parties and voting campaigns, contributing to the group's rapid rise, including a Billboard "K-Pop Rookie of the Month" recognition in late 2024 and millions of views on short-form content by early 2026. Sungho's connection to his supporters is further highlighted by moments where members openly watch and discuss fan edits, fostering a reciprocal relationship built on mutual appreciation of their music and performance. The narrative around Sungho is one of emerging stardom, marked by significant milestones like the kickoff of their first world tour, "Knock On Vol. 2," at Seoul's KSPO Dome in July 2026, and international expansions into markets like Chicago and Singapore. Despite these achievements and a growing global footprint, iFANN's Global Fame Engine has evaluated Sungho but does not currently place him in the published rankings (Global Top 1,000 or a Top-100 scope list). Consequently, he holds no placement in the Global Top 1,000 or any scope-specific list at this time.[edit]

Park Sungho serves as both the leader and main vocalist of BoyNextDoor, a role that highlights his responsibility and vocal prowess, particularly when handling challenging high notes. His stage name is a direct abbreviation of his birth name, maintaining a simple identity that fits the group's approachable concept. Hailing from Wonju in Gangwon Province, he stands out as one of the few idols representing smaller cities within the industry. Although charismatic during performances, he is described by fans as notably reserved in his personal interactions off-stage. His training under KOZ Entertainment, a label founded by hip-hop icon Zico, infused his musical foundation with distinct R&B and hip-hop influences. Beyond his professional duties, Sungho has been part of defining moments in the group's young history, such as the energetic launch of their "Knock On Vol. 2" world tour in July 2026. The group also made waves internationally with a scheduled concert at the Singapore Indoor Stadium in October 2026 alongside NCT 127. Additionally, their appearance at Lollapalooza 2025 in Chicago provided exclusive photo diaries that captured their experience, further cementing their status as rising stars in the global K-pop scene.[edit]

Sungho has not publicly disclosed details about his family, including his parents or siblings, maintaining a private personal life typical of many K-pop idols. He was born and raised in Wonju, Gangwon Province, but specific information about his household or upbringing is not available. As of 2026, he lives in Seoul while promoting with BoyNextDoor. No pets or family stories have been shared publicly.[edit]

Sungho is closely associated with his BoyNextDoor groupmates: Taesan, Riwoo, Jaehyun, Leehan, and Woonhak. He also works with Zico, the founder of KOZ Entertainment, and the label's producers and choreographers who shape the group's sound and performances.[edit]

As of 2026, Sungho has no publicly confirmed romantic relationships. He has not been linked to any dating rumors or scandals, maintaining a clean public image typical of many K-pop idols. His personal life remains private, and he is currently reported as single with no known children.[edit]

As things stand in 2026, research by the iFANN Editorial Team puts Sungho's estimated net worth at $1 Million. His primary income streams are derived from BoyNextDoor's album sales, digital streaming numbers, concert tours, fan meetings, and merchandise sales. Operating as a rookie group under the HYBE subsidiary KOZ Entertainment, earnings are distributed among members following standard company deductions. While the group has secured various brand partnerships, individual endorsements specifically attributed to Sungho have not been publicly reported. There are no known personal business ventures or real estate investments linked to him at this stage. Net worth figures for K-pop idols, particularly those in the early stages of their careers, remain speculative due to limited public financial disclosures.[edit]
