Kim Se-jeong joins 'The Seasons' lineup, 10 years on from I.O.I debut
Kim Se-jeong, now 29 and signed to BH Entertainment, appeared on *The Seasons*—a decade after her *Produce 101* breakthrough.
Kim Se-jeong (29) announced her appearance on the music program The Seasons with a short post reading "더시즌즈 앙" — her latest stage since a busy run of performances earlier this year.
Earlier in 2026, she appeared on KBS 2TV's The Seasons – 10cm's Comfort, where she performed IU's "To My Name" (이름에게), describing it as the song she uses to check her vocal progress every year. That same broadcast featured a dance medley of I.O.I and Gugudan tracks to mark her 10th debut anniversary, and a performance of her single Solar System (태양계) alongside guitarist Jeok Jae.
Se-jeong first broke through via Produce 101 in 2016, finishing 2nd overall while holding debut eligibility in every episode. She'd already competed on K-pop Star Season 2 and Superstar K5. She went on to debut as main vocalist of Gugudan. "너무너무너무" from the I.O.I era reached No. 1 on music broadcasts; her solo "꽃길" topped both the digital charts and music programs.
On the acting side, she starred in Office Blind Date (사내맞선), played Counter Hana in OCN's Extraordinary Rumor (경이로운 소문), hosted Paik's Street Restaurants, and appeared on mystery variety show The Culprit Is You!. She recently won Best Supporting Actress at an acting awards ceremony.
In March 2026 she ended her contract with Jellyfish Entertainment and signed with BH Entertainment, where she is now labelmates with fellow I.O.I alumna Jung Chae-yeon. She continues vocal and voice lessons to develop her singing while advancing her acting career.
