The “other main characters” — the cells inside TVING’s original Yumi's Cells 3 — are going viral and sparking divisive reactions among viewers.
Episodes 5–6 of Yumi's Cells 3, released on the 27th, featured Soon-rok (played by Kim Jae-won) confessing his feelings after realizing he likes Yumi (played by Kim Go-eun). In the final moments, Soon-rok told Yumi, "I think I like you, writer," cranking up the tension.
Meanwhile, across social media and online communities, drama fans are flooding in with takes about the in-show cells, with opinions split — especially over the Love Cell versus the Writer Cell.
The Love Cell was originally Yumi’s Prime Cell — the one cell with the strongest influence over her actions. In earlier seasons, Love reigned as Yumi’s Prime Cell. But after heartbreaks with Goo Woong (Ahn Bo-hyun) and Yoo Babi (Park Jin-young), Love turned dark, and Yumi herself stepped into the cell village to usher in a new Prime Cell era: the Writer Cell.
While Yumi put romance on pause and focused on her career, the Writer Cell rose as the Prime Cell and took charge. Then Soon-rok appeared — thawing out the long-frozen Love Cell, which resurfaced and evolved back into the Prime Cell.
Fans reacted, saying things like, "It’s sad that the Writer Cell, which took years to build up, gets pushed aside overnight," and "Love is doing too much." Others clapped back with comments like, "Let’s remember it’s just a drama," and "Only in K-culture do we over-immerse in cells," adding a dose of humor to the debate.
Meanwhile, episodes 7–8 of Yumi's Cells 3 drop on the 4th at 6 p.m. KST exclusively on TVING. On tvN, episode 6 airs on the 28th, with new episodes every Monday and Tuesday at 8:50 p.m.
