And now it is time to wait no longer, and our favorite cells have been restored to business in Yumi’s Cells season 3! It is like following a best friend through the ups and downs of her life since Yumi has the most relatable and internal crisis as she goes through her thirties. Season 3 episodes 1 and 2 started on a very strong note in the same way that I fell in love with the show in the first place, although I already have a few bones to pick.
The Journey So Far
Season one introduced us to Yumi (Kim Go Eun) and her cute brain village. I saw her recover from a savage heartbreak and fall in love with Woong (Ahn Bo Hyun). Their romance was crude and natural, revealing how pride and time can separate two individuals. It was a sweet-sour start that set the stage for Yumi’s huge personal development.
In season 2, the emphasis was placed on Bobby (Park Jin Young). He was the green-flag boyfriend until the tiniest crack in his heart altered everything. Yumi preferred herself to a relationship that she could no longer consider safe and eventually followed her dream of being a writer. These previous chapters made Yumi the strong and independent woman I see on my screen today.
EP. 1: The Routine of Success

The season 3 premiere sees Yumi at the peak of her career. She owns her writing studio and even a personal assistant! The star of the village is obviously her Writer Cell, who now has a flashing new outfit and is bad-ass on the front lines. But the honey of success has changed her daily life in some way that I did not anticipate.
The climax of the show is the skydiving scene. It embodies the disorganized energy that I had been so deprived of. Yumi is having a good life, yet her Love Cell is still slumbering. The shift of the emotional drama of Season 2 to this subdued, professional achievement feels real and justified.
The animation is of high quality. Whenever the cells scramble to act in response to a social situation, it comes as though a call-out to a person. The wit is keen, and the action is fast, and the half-hour episode passes in what seems like a few minutes.
Episode 2: Meet the Reindeer
The second episode reveals the new source of Yumi’s frustration: Shin Soon-rok (Kim Jae Won). He is a fact and boundary-obsessed editor at Julie Publishing. Their introduction is a fiasco of a stack of strawberry and cream bungeoppang. His brash character is a complete wake-up call to his dormant cells, Yumi.
Soon-rok is also an interesting character to the cast. He is young, rational, and appallingly crass. He can commend the writing of Yumi via a brilliant email, but at the same time, he slanders her driving abilities in front of her. This hate-view romance energy is already making me feel more interested than any regular love at first sight cliché.
The cells are chaotic as usual. Reason Cell is working overtime to ensure that Yumi remains professional, and Naughty Cell is already seeking indications of a new crush. The village is livelier than the rest of the seasons, and new cells emerge to symbolize the life of a writer like Yumi.
The Slapstick Shift
Although I am pleased to have the cell village back, I was a bit jarred at the transition to Season 3. It is far more of a slapstick comedy than the earlier seasons. I am a big laugher, and some of the jokes seem a little artificial in comparison to the natural, gut-wrenching jokes of the old.
I have to speak about the casting also. The chemistry is a little stiff at this point, but the new lead is good. Soon-rok comes across as slightly robotic. This reversal comes after the amazingly warm-heartedness of the preceding male protagonists. I desire to experience that spark, and at this moment, it seems more of a cold business deal.
Also, the cell village drama is beginning to become a distraction of sorts. Episode 2 did have instances where the animated bits literally came in the middle of the emotional action of the live-action sequences. I would just as much like to see what Yumi would do in real life as I would like to see what the cells would debate. At this moment, the balance is a little imbalanced.
The Evolution of Yumi
Yumi and her development are the absolute anchor of this show. She was characterized by her desire to have a family in Season 1. In Season 2, her love affair with her partner characterized her. Yumi is eventually characterized by her name in Season 3. She is no longer the girlfriend of Woong, a soulmate of Bobby. She is Yumi, the Author.
Her inner monologue has changed considerably. She is more demanding of her editors and more guarded over her own time. This is the most inspiring of all versions of Yumi. She demonstrates that there is still much living and excitement to be made above thirty, even though you might not have it all figured out.

Although I was at first reluctant, Soon-rok adds much-needed tension to the program. Once the perfection of Early Bobby is achieved, it is truly refreshing to have a genuinely annoying male lead. The way he challenges Yumi is intellectual and not romantic. Their jokes are like chess, and I am eager to know who will take the next step.
He embodies the idea of a boundary, and it is exactly what Yumi has to journey through at this moment. As long as the writers can make the robotic corners less sharp and locate the heart behind his rational shell, it may be the most adult of relationships in the series.
Long-time fans like me will find these opening episodes a hug. Yumi is the most familiar character in the K-drama world. The quality of production is high, and a new plot is likely to give us a lot of laughs and heart-fluttering moments, as soon as we get over the initial awkwardness. I am buckled and waiting out the rest of this emotional rollercoaster.
