Get ready for another emotional rollercoaster—Yumi's Cells is back to awaken your love cells once again.
🧠 Live-Action x 3D Hybrid K-Romance Returns
TVING's original hit series Yumi's Cells (written by Song Jae-jung & Kim Kyung-ran, directed by Lee Sang-yeob) is officially returning for Season 3, three years after its last season.
The new chapter follows Yumi, now a successful romance novelist, and the colorful, chaotic "cells" that make up her inner world.
The show has long been praised for its genre-blending format—mixing live-action with 3D animation—and its refreshing, relatable take on everyday romance and personal growth.
🌟 Familiar Faces + A Fresh Lead
Kim Go-eun returns in the lead role of Yumi, reuniting with director Lee Sang-yeob and writers Song Jae-jung and Kim Kyung-ran.
New to the cast is rising actor Kim Jae-won, who joins as the new male lead "Soon-rok", a character sure to bring fresh chemistry and heartfelt tension.
💌 A Romance Between Logic and Emotion
Yumi has achieved her dream of becoming a top romance author, but when it comes to love, she's still navigating the unknown.
Enter Soon-rok, a seemingly cold and logical PD at Julie Publishing House. As he's assigned to work with the emotionally-driven Yumi, unexpected sparks begin to fly—setting the stage for a delightful older woman/younger man romance.
