The cast includes Kim Go-eun, Kim Jae-won and Jeon Seok-ho. Because director Lee Sang-yeop and Kim Go-eun were also involved in 'Yumi's Cells Season 2,' as director and cast member respectively, Season 3 can be seen as a story continued by the same two people. For viewers who watched Season 2 first, there is fun in reading Yumi's changed circumstances against the earlier story.
It is a TVING Original, available by subscription from March 17, 2026. The running time is 65 minutes. Since it sits in a position where viewers who have finished Season 2 can continue straight on, the better you remember the emotional thread of the earlier season, the more clearly the change brought by the new character comes across.
