Doyeon
Kim Doyeon helped build the original eleven-member I.O.I. This page follows the whole career—not only the reunion clip currently eating the timeline.
Early life and the road into entertainment
Doyeon entered Produce 101 with Fantagio and quickly became known for long performance lines, dry humor, and a fashion-editorial presence that looked unusually finished for a trainee. She ranked eighth and joined I.O.I.
Produce 101 and the original I.O.I chapter
I.O.I formed through the first season of Produce 101 and debuted on May 4, 2016. The contract was temporary by design, which meant the group learned to perform, promote, split into a seven-member unit, return as eleven, and say goodbye while the countdown clock remained visible.
Doyeon belongs to the full eleven-member lineup: Lim Nayoung, Chungha, Kim Sejeong, Jung Chaeyeon, Zhou Jieqiong, Kim Sohye, Yoo Yeonjung, Choi Yoojung, Kang Mina, Kim Doyeon, and Jeon Somi. A promotion lineup can change. The historical membership does not.
After I.O.I: the career did not freeze in 2017
After I.O.I, she debuted in Weki Meki with Yoojung and expanded into acting, modeling, and fashion work. The 2026 reunion brings her back beside members whose careers scattered across completely different corners of entertainment, which is precisely why the group now feels more textured.
2026: I.O.I : LOOP and “Suddenly”
I.O.I returned for its tenth anniversary with the six-track mini album I.O.I : LOOP and the title song “Suddenly.” Nine members participated in the new recording and promotions. Mina and Jieqiong were unable to join because of prior commitments; neither was announced as having left the group.
The project matters because the members returned with adult careers, different companies, and creative credits of their own. Somi co-wrote “Suddenly,” while other members contributed elsewhere on the album. This is not eleven rookies waiting for a label to tell them who they are anymore.
Performance identity
Doyeon does not need frantic movement to hold a frame. Her best moments are often the ones where everyone else is working harder and she simply knows where the camera is.
RaeRae take: Reunion coverage gets lazy when it treats every member as a before-and-after photo. The interesting story is what each woman learned elsewhere—and what becomes visible when they stand together again.
Fandom notes without rewriting history
- Fandom: U&I.
- Full membership: Eleven. Always distinguish membership from a specific promotional lineup.
- 2026 promotion: Nine members recorded and promoted most of LOOP.
- Archive track: “Goodbye With A Smile,” recorded in 2016, preserves all eleven voices.
