Circumstantially alone, Ha-ni follows Seung-jo around campus and right into the Top Spin Tennis Club. Having never played before, she's out of her league, and the training director, a student himself, is a Jekyll and Hyde type, friendly elsewhere but a monster on the court. There too she finds Yoon He-ra, a new rival for Seung-jo's hard-to-reach affections and second-best at tennis (after Seung-jo). As Ha-ni obsessively follows Seung-jo, Bong Joon-gu likewise follows Ha-ni, having taken a second job in the college cafeteria to be near (and to follow) her into classes. As Oh Ki-dong learns of Bong Joon-gu's devotion to his daughter, he decides it's time he and Ha-ni moved out on their own once again.
