Tving’s original series, Yumi's Cells Season 3, arrives April 13, debuting with a teaser poster that highlights Kim Go-eun’s sunny, effortless smile.
After a three-year hiatus, the third season finds Yumi (Kim Go-eun) established as a bestselling author. Her quiet, predictable life is suddenly upended by an unexpected arrival that sets her inner “cells” in motion, launching a bittersweet, laugh-and-cry romance. With her writer’s dream fulfilled, the once-tranquil cell village stirs again as an unpredictable love story takes shape. On screen, Kim Go-eun pairs opposite Kim Jae-won in a tender, age-gap romance.

The teaser poster captures Yumi’s radiant smile, while the tagline — "It's been a while, this soft, fluttering feeling" — signals the start of a new chapter that will rattle her cell village.
Kim Jae-won plays Sun-rok, an editorial PD at Julie Publishing who, despite a sweet face, is unafraid to deliver blunt truths. The chemistry between Yumi, a successful romance novelist who still wrestles with matters of the heart, and Sun-rok, a PD with unexpected depth, sets up a warm, emotionally resonant dynamic. Audiences will be watching to see how Kim Go-eun and Kim Jae-won bring this slow-burn relationship to life.
Yumi's Cells Season 3 premieres on Tving on April 13, with two episodes released exclusively each Monday at 6:00 PM. tvN will broadcast one episode each week on Mondays and Tuesdays at 8:50 PM.
