Taehwan
Oh Taehwan (오태환) is a South Korean singer and the eldest member of boy group KEYVITUP under iNKODE Entertainment. Born on June 6, 2004, Taehwan studied K-Pop at the Dong-Ah Institute of Media and Arts, building his vocal foundation and stage craft at one of Korea's leading entertainment-focused universities.
He built early industry experience through competition, placing 30th on the survival show PROJECT 7 and returning to contend on FAN PICK before iNKODE came calling. He was introduced as part of the INTHE X trainee project in November 2025 and officially confirmed as a KEYVITUP member on February 25, 2026. KEYVITUP debuted on April 8, 2026, with their self-titled EP under iNKODE Entertainment, the label founded by Kim Jae-joong.
As the group's eldest, Taehwan carries a grounding presence that the other members lean on. They affectionately call him Mochi, a Japanese word for rice cake that captures his soft-spoken warmth. His MBTI is INFP (previously ENFP), and his role model is NCT's Haechan. Hobbies include watching films, playing games, painting, and drawing -- a creative interior that informs everything he does on stage.
