Ho-Jung (Chae Rim) is a cute, naive girl who often falls head over heals with the wrong guys. Both Ho-Jung and Kyu-In (So Ji Sup), her neighbor, are idealistic about love. They start off on the wrong foot and treats each other as if they were siblings, constantly fighting. Ho-Jung's friend Cha Hee (Choi Yoon Young) has a thing for Kyu-In and Ho-Jung later realizes that she too has feelings for him. Ho-Jae (Kwon Sang Woo), Ho-Jung's brother, is a player, who has good physical features. Things start to get complicated for Ho-Jae when he falls for Ho-Jung's friend Soo-Ji (Lee Hee Jung), who does not have a physical appeal but has a good personality and intelligence.
