This is a typical ”opposites attract” series, and maybe the funniest Korean rom-com so far.

Kim Jin Woo (Kim Sung Hyun) is a shy and serious student who liked to organize his life by making lists, and who's had a secret crush on Jung Ki Sub (Nam Shi An), a womanizer who has been unable to have a serious relationship. When Jung Ki crashes at Kim Jin's house, Kim Jin tries to get rid of him at first, but after some time realizes that he loves the lively Jung Ki, who actually does everything to match Kim's list of requirements of an ideal partner. Not only puts he on a ridiculous wig, but he even has a mole tattoed on his face.

Among all the hilariously funny scenes, the series gains depth when the protagonists' backstory is gradually revealed, which is also true about the story of the wonderful second couple, Ji In Ho (Ahn Se Min) and Choi Balgeum (Jung Yep Joon).

As I said, the series is freaking funny, but thanks to a well-written script, the characters are described and developed better and more sensitively than in many much longer series.
