Hana Uzaki is thrilled to discover that she is attending the same college as her fellow high school upperclassman, Shinichi Sakurai. However, after a year of watching him just laze around, she comes to the conclusion that he has turned into a loner. She decides to spend as much time with Shinichi as possible, believing that he is an introvert or intimidating, which is uncool and unacceptable. Beginning her project to have Shinichi experience a fun lifestyle, Hana stalks him like an annoying pest. Will Shinichi ever make her understand that he prefers doing things by himself, or will he be won over by Hana's zany charm?
