Shizuku is the female protagonist of the story. A high school student who starts off only thinking and interested about studying and getting the top grades in the class and doesn't have feelings for other things or everyone around her. She meets Haru Yoshida for the first time delivering class printouts to him. Originally not caring for him; as they get along, her perspective in life was changed as she begins to experience things outside of studying and feelings she has never felt before.

Haru Yoshida (吉田 春)
Voiced by: Kenichi Suzumura (drama CD), Tatsuhisa Suzuki (anime)
Birthday: April 2
Haru is the male protagonist of the story. He is a high school student who sits next to Shizuku in class. He is a delinquent boy who is absent for a long time after getting in a fight early in the story. Despite being a trouble maker, he is a passionate boy who helps others and can achieve high grades with little effort. He does not like going to school because most people see him as a threat and are afraid of him, saddening him because he is unable to make real friends. After meeting Shizuku, he takes her as his first real friend and starts to attend school, falling in love with her in the process. He also keeps a rooster and brings it to school everyday despite his teacher's disapproval. He has somewhat of a perverted mind, openly saying to Shizuku that he would "do" her and has "dirty thoughts" about her. It is unclear whether or not he actually thinks before he speaks.
At first he was shown to be a delinquent but as the story unfolds it was revealed that Haru was rather a shy and innocent boy, though he has bipolar tendencies, probably because he hasn't interacted with many people in the past.
