Actress Yoon Yu-seon appeared in the final episode of TVING’s original series “Yumi’s Cells” Season 3, adding warmth to the drama’s closing.

Yoon played Yeong-sim, the mother of Yumi (Kim Go-eun), in the last episode of the recently concluded season.

“Yumi’s Cells” Season 3 follows Yumi, now a star writer, as she meets an unexpected figure, Sun-rok (Kim Jae-won), and falls in love again.

In the series, Yeong-sim is a steady presence by Yumi’s side and looks on Sun-rok with kindness. Though her screen time was brief, Yoon delivered a calm, gentle performance that reinforced the character’s warmth. Returning as part of Yumi’s family after Seasons 1 and 2, she helped bring a familiar tone to the finale.

The cameo also aligns with Yoon’s recent run of projects. She returned last month in Netflix’s “Bloodhounds” Season 2 as Yoon So-yeon, the mother of Geon-woo (Woo Do-hwan). The action series, starring Woo and Lee Sang-yi as they take on an illegal boxing league, rose to No. 1 in Netflix’s non-English TV category after its release.

In “Bloodhounds” Season 2, Yoon portrayed a mother determined to protect her son from injustice, using restrained emotion and a firm gaze to add weight to the story. Her role helped anchor the characters’ emotional arc amid the high-tension action.

Yoon has also expanded her work beyond acting into variety shows and hosting. She recently appeared on an entertainment program with her husband, attorney Lee Seong-ho, sharing their daily life as a couple. She also took on her first solo MC role on Channel A’s “The Body Geniuses,” a tailored health-solution program offering information for healthier living, meeting viewers with a steady, approachable hosting style.

With steady work across dramas, streaming series, variety programs and hosting, Yoon continues to broaden her range, with attention on what she will do next.
