Kim Sejeong

Kim Sejeong (김세정) is one of the clearest examples of a Produce-era breakout turning into a durable multi-lane career. She first became unavoidable through I.O.I, carried that momentum into gugudan, and then avoided the post-project trap by building a public identity that could hold as singer, variety personality, and lead actor at the same time.

That balance is what keeps the page current. Sejeong never stopped making music, but the broader market now reads her as a bankable singer-actor whose catalog and screen work reinforce each other instead of competing for attention. The 2026 move to BH Entertainment sharpened that positioning, placing her inside a company with heavier actor infrastructure just as the next drama cycle demanded a bigger long-form screen frame.

Her current era is less about survival-show nostalgia and more about range. Business Proposal made her a wider mainstream face, Brewing Love kept the acting lane hot, and MBC's The Moon Flows in This River pushed her into her first historical-drama lead. Add the solo music run, the Longchamp and REJURAN endorsement lane, and the scale of her public fan base, and Sejeong reads as a fully stabilized star rather than a former idol searching for a second act.

Fans Also Ask

How did Kim Sejeong become famous?
Kim Sejeong broke out through Mnet's <em>Produce 101</em> in 2016, where she finished second and joined <a href="/artists/ioi">I.O.I</a>. She then re-debuted in <a href="/artists/gugudan">gugudan</a> and built enough recognition to turn that early idol momentum into a long-term singer-actor career instead of a one-cycle survival-show peak.
Was Kim Sejeong in both I.O.I and gugudan?
Yes. Kim Sejeong was part of the project group I.O.I after <em>Produce 101</em> and later promoted as a member of gugudan under Jellyfish Entertainment. Those two chapters formed the base of her idol career before her solo discography and acting work widened her audience well beyond the original survival-show fandom.
What is Kim Sejeong's latest drama direction?
Kim Sejeong is confirmed for MBC's <em>The Moon Flows in This River</em>, a historical romance that marks her first full sageuk lead. The project matters because it pushes her into a new acting lane after stronger contemporary-drama visibility through titles such as <em>Business Proposal</em> and <em>Brewing Love</em>.
Which agency is Kim Sejeong with now?
Kim Sejeong moved to BH Entertainment in March 2026 after a decade with Jellyfish Entertainment. The switch aligned her with a company known for actor management, which makes sense given how central drama work has become to her public profile even as she keeps her solo-music identity active.
Is Kim Sejeong mainly a singer or an actress now?
She works as both, but the strength of her profile comes from not having to choose one lane. Sejeong still releases music and carries a real solo fan base, yet her acting work now has enough scale that she is better understood as a fully cross-functional singer-actor rather than a former idol dabbling in drama.
