Keeho

Keeho (기호), born Yoon Kee-ho (윤기호) on September 27, 2001, in Toronto, Canada, is the leader and main vocalist of P1Harmony. Known by his English name Stephen Yoon, he stands 179cm, holds an INTP personality type, and was the first member of P1Harmony to be publicly revealed. His younger brother is Yechan of 82MAJOR, making the Yoon family a genuinely K-pop household. Keeho grew up steeped in a love of music: his favorite artists include Daniel Caesar, SZA, Frank Ocean, H.E.R., SiR, Alex Isley, Yebba, PJ Morton, Jazmine Sullivan, and Tori Kelly. He carries that deep affection for neo-soul and R&B vocals into P1Harmony’s more emotionally resonant tracks, while his English fluency opened P1Harmony to global audiences long before the group released an English EP. His VLives conducted entirely in English became a pipeline for international fans to connect with P1Harmony in real time. A 2021 cover of John Legend’s "All of Me" performed at the P1uspace fan event became one of the group’s most shared clips. Keeho’s leadership style is candid, warm, and self-aware. He describes himself as patient, kind, and funny, and his life motto, "Don’t take life too seriously," comes through in how openly he engages with fans. From the Disharmony series to the Billboard 200-charting EP EX (2025) and the incoming mini-album Unique (March 12, 2026), Keeho remains the human anchor of P1Harmony’s global identity.
