What is the Plot of the Series?

Following the daily life of Yumi, the series tells about this 32-year old ordinary office worker. She is not good at expressing her feelings and that’s the main reason for her being single for so many years. The series follows her as she grows as a person and finds happiness through her romantic relationship and work. The cells in her body represent her varying emotions such as love, violence, rationality, good, and bad. The cells in her brain work actively for her as they try to deal with her emotions and troubles.

Yumi likes her younger colleague Wook. However, a lot of things prevent her to pursue him. One of them being her insecurity for her age and the other reason is her love rival Ruby. Yumi is unwilling to take the risk even with her cells working to do anything for her happiness. Moreover, Wook approaches Yumi, wanting to talk to her and go out with her. This gives Yumi the impression that he is interested in her too. However, Wook sets her up on a blind date with his friend, Goo Woong. Also, Yumi learns that Wook is homosexual, ruining every chance of her being together with him.

This upsets Yumi and she unintentionally ruins her blind date with Woong. In the middle of the date, she faints due to excessive stress and Woong carries her to a nearby hospital. They eventually get together. However, after Yumi expresses her thoughts of marrying him, Woong denies the idea since his game studio is unstable. Since he is unsure that he can keep her happy and economically stable, he never gave marriage any thought. The series continues with Yumi’s romantic struggles as her cells work hard to make the right decision for her happiness.
