What’s Yumi’s Cells All About?
Based on the popular webtoon of the same name, Yumi’s Cells tells the story of an ordinary office worker named Yumi (played by Kim Go Eun) — from the point of view of the many brain cells in her head controlling her every thought, feeling, and action.
The concept of visualising inner emotional conflict through animated brain cells is what makes this series unlike anything else in K-drama. It’s part rom-com, part psychological drama, and 100% addictive. The webtoon format it’s based on is a uniquely Korean digital comics tradition that has spawned countless hit adaptations — and Yumi’s Cells is one of its finest.
