JONGSEOB is a rapper, dancer and the youngest member of P1Harmony. He was credited as a lyricist across all six tracks on the 2026 ninth EP UNIQUE and remains one of the group’s most active songwriting contributors.

P1Harmony remains a six-member group under FNC Entertainment. Group awards, chart records and tour achievements are kept on the main P1Harmony page instead of being presented as this member’s personal awards.

JONGSEOB does not currently have a standalone solo album. Individual performance clips and covers are therefore not treated as a solo-album YouTube section on this profile.
