Web Comic / Yumi's Cells

Go To

Yumi's Cells is a Korean Webtoon by Donggun Lee.

Yumi Kim is a 32-year-old office worker. Somewhat shy and introverted, she has trouble socializing, but likes cute things and still hopes she can find her One True Love.

This is her story, but also the story of her brain cells.

Represented as little blue-suited men and women such as the Anger Cell, Rational Cell and Emotional Cell; they argue, take counsel together, and occasionally fight each other for control. All in an attempt to keep Yumi functioning day-to-day and prevent her from suffering too many embarrassments.

The official English translation can be read here.

See also Inside Out, the Pixar film with a very similar theme.


Contains examples of:

  • All Women Are Lustful: Yumi's Naughty Cell has to be kept in check by the others.
  • Bastard Boyfriend: Mildly zigzagged with her ex. Confidence being his prime cell, he swaggers back into her life, assuming she will fall back into his arms. When she stands up to him and gives a firm "no", he seems to get a grip on himself and backs off.
  • Bridal Carry: When Yumi collapses with a fever, Woong carries her to the hospital like this. Even thinking "Carry my princess!"
  • Clingy Jealous Girl: Woong's best friend, Sia, has her feelings for Woong arise again when Woong and Yumi start going out. She and her cells have been hiding repressed emotions for Woong because of fear that it would get in the way for her job.
  • Dream Within a Dream: Chapter 95 has Yumi waking up at work and talking about her wonderful dream of a romance with Woong (who is a movie star in a relationship with Sia,) then waking up from that dream. Cue "OMG AUTHOR YOU JUST GAVE ME A HEART ATTACK" comments from the readers.

  • Heroic Resolve: When Woong needs to carry Yumi several blocks to the hospital, his brain cells summon this.
  • Loners Are Freaks: Yumi's still single partly because she avoids social activities such as going out drinking with her coworkers.
  • Manchild: The Hunger Cell is a giant building-sized child that is constantly snacking. The others try to keep him under control so Yumi doesn't overeat, but he can get very cranky.
  • Mistaken for Gay: Inverted with her coworker Wook. She pines for him and is overjoyed when he asks her out... until he reveals he's gay and is actually trying to set her up with a friend of his, Woong.
  • Never My Fault: Yumi's Judge Cell embodies this part of her personality, consistently insisting that other people are at fault whenever she suffers from relationship problems.
  • One Steve Limit: Averted, her coworker Wook turns out to have the same name as her ex-boyfriend and is likely the reason she fixates on him at first.
  • The Power of Love: The Love Cell has a special pink costume and is the most powerful of all. Unfortunately, she was De Powered and put into a coma after Yumi suffered a break-up a few years before the story begins. She starts recovering as Yumi finds potential new romance.
  • Second Love: Yumi went through a break-up and became emotionally withdrawn. She'd like to find romance again and after a false positive with Wook, she does find it in Woong. Later in the story after the two's breakup, this trope applies to Babi.
  • Shout-Out: When Yumi's brain cells are arguing over whether to buy Woong a gift of expensive shaving cream, Love Cell flies in and calls for a vote. She asks who the dissenters are while holding a pencil and a Death Note... and suddenly there are no dissenters.
  • Shrinking Violet: Yumi struggles to speak her mind and stand up for herself. After she starts going out with Woong, she does become more confident eventually.

How well does it match the trope?
