Her cells try to make her happy at all cost, even if it means not taking the risk of confessing to your crush. For this reason, Yumi remained single.

Until one day, her blind date with Goo Woong results into a relationship. Goo Woong is a bit nerdy guy who likes video games so much that he has a game studio of his own.
