Kim Go Eun and Kim Jae Won’s Behind-the-Scenes Bond in Yumi’s Cells 3 Will Melt Your Heart

Sometimes, the most magical moments happen when the cameras stop rolling. That’s exactly the case with Yumi’s Cells 3, where the latest batch of behind-the-scenes photos has fans losing their minds — for all the right reasons.

Kim Go Eun and Kim Jae Won may play two characters who get off on the wrong foot on screen, but off-screen? Pure, unscripted warmth.

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.

The BTS Moments That Have Everyone Talking?

The newly released behind-the-scenes photos are genuinely sweet. In one photo, Kim Jae Won thoughtfully shields Kim Go Eun from the sun with his hand; in another, they playfully joke around while talking to the director between takes. The two co-stars can also be seen posing for photos together when the cameras aren’t rolling.

And that train station moment? A photo captures the memorable moment when Yumi and Soon Rok brushed hands at the Busan train station, which made not only Yumi’s but also viewers’ hearts flutter. soompi Even the still photo gives you butterflies — imagine watching it on screen.

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.
