What’s Yumi’s Cells 3 All About?
Based on the popular webtoon of the same name, Yumi’s Cells tells the story of an ordinary office worker named Yumi — from the point of view of the many brain cells in her head controlling her every thought, feeling, and action. In Season 3, Kim Jae Won plays Yumi’s new love interest Soon Rok, an editorial PD at Julie Publishing.
It’s the kind of show that makes you feel everything — anxiety, butterflies, second-hand embarrassment — all at once. And these BTS moments prove the cast is just as endearing off-set.

What’s Coming in Episodes 5 & 6?
The production team isn’t holding back on the anticipation. The team teased: “In Episodes 5 and 6, as Ju Ho aggressively pursues Yumi, Soon Rok will also begin to change. Please look forward to seeing what kind of variable Ju Ho will introduce into the relationship between Yumi, who has feelings for Soon Rok, and Soon Rok, who has started to change because of Yumi.”
Translation? A love triangle is heating up — and it’s going to be deliciously complicated.
