Hye Nim's brother (Kim Yu Suk) fell in love with a Korean girl (Rai Su Min) and moved back too Seoul to live together. It's been one year since they moved and now both you and Hye Nim have gratuated from your high school and before entering the university -you both got accepted to- you decided to go to Seoul for the summer vacation to visit Yu Suk and Su Min for a month or so. What you didn't know was that fate decided to play a game with your lovelife.
