The beloved Yumi’s Cells universe is officially expanding! Fans were thrilled after new clips surfaced online showing Kim Go Eun and Kim Jae Won filming scenes for the highly anticipated Yumi’s Cells Season 3. The duo will portray the next chapter in Yumi’s emotional and romantic journey, with Kim Jae Won taking on the role of Shin Soon Rok, the new male lead who follows Goo Woong (Ahn Bo Hyun) and Yoo Babi (Park Jin Young) from the previous seasons. The show is set to premiere in the first half of 2026 on TVING.
In videos shared by fans who spotted the shoot, Kim Go Eun and Kim Jae Won can be seen walking hand in hand along a busy street — a sweet first look at Yumi and Soon Rok’s dynamic. The scene captures a light yet emotionally charged atmosphere as the two stroll together, with Kim Jae Won’s character gently pulling Yumi along while she matches his stride. Both stars were dressed in formal attire — Yumi in a sleek blouse and trousers, and Soon Rok in a fitted suit, signaling a possible office or professional setting tied to their budding relationship.
Adding to the excitement, Kim Jae Won shared a subtle Yumi’s Cells-themed easter egg on his Instagram story. He wore a black T-shirt featuring Yumi’s signature blue cell character, captioning it with the word “cute”. The post quickly caught fans’ attention, further confirming his enthusiasm for his new role and the beloved world of Yumi’s inner “cells.”
The new season will also see the return of Lee Yubi, Jo Hye Jung, and Baek Na Hee, with Choi Daniel joining the cast in another major role.
