Profile
YEO ONE (Yeo Chang-gu) is a PENTAGON vocalist and performer who has also participated in acting and musical-theatre projects. He debuted with the group on October 10, 2016.
In February 2026 he issued the independently credited digital single Run it up. Music services list the single under YEOONE rather than under PENTAGON, so it qualifies for an individual SOLO designation. His television soundtrack appearances and music performed with PENTAGON are not automatically treated as solo albums.
He participated in the seven-member tenth-anniversary reunion of PENTAGON in September and October 2026, including the Coward single and anniversary shows.
