The newly released poster features Yumi (Kim Go Eun) and Shin Soon Rok (Kim Jae Won) dressed in all white, cheeks pressed together adorably as confetti rains around them — their animated cells joining together on top of a festive cake. It is the visual definition of a happy ending, and it is clearly designed to tug at every heartstring before the credits roll for the very last time.
The Story of Yumi’s Final Chapter
Yumi’s Cells is a cell-based psychological romance that unravels the daily life of an ordinary office worker Yumi through the eyes of the cells in her head. Season 3 picks up with a Yumi who has completely transformed. Wikipedia
No longer an employee of Daehan Noodles, she has realised her dormant passion for writing and has become a celebrated author of romance novels. With adoring fans and very proud parents, Yumi seemingly has everything she could want — or does she? South China Morning Post
Her days have turned dull and monotonous — until a man named Shin Soon Rok steps into her life. Facing this younger man, Yumi discovers a new kind of love: unexpected, disarming, and deeply stirring. MyDramaList
Sin Sun Rok, an editor in his 20s at Julie Publishing, is all about facts, logic, and boundaries, feeling perfectly relaxed when staying home alone — but as Yumi starts to invade his world, he draws a line, only to find himself slowly, irresistibly falling for her. MyDramaList
