A transfer student at her new high school, Chihiro Watanuki is helped out by a student while finding a place to park her bicycle. After her class introduction concludes, she finds out that her seat is right next to the boy who helped her earlier that day. Her classmates inform her that he is Yuji Yugami, the ace of the Baseball Club. However, they also advise her to stay away from him, as he is known to be a bonafide weirdo and his actions are incomprehensible to most people. Unconvinced, she attempts to interact with him, quickly realizing that he is nothing but a pain to talk to and that the rumors were indeed true. Shortly afterward, Chihiro gets entangled in a sticky situation with the third-years, but Yuji once again comes to her rescue, albeit for his own self-righteous reasons. Convinced that there is more to him than meets the eye, she is determined to treat him without bias and to live a normal high school life surrounded by friends.
