Mizutani Shizuku (Tsuchiya Tao), who has excellent academic performance, has a cold personality and is unwilling to deal with people around her. On this day, she was assigned by the teacher to deliver homework to a boy who had not come to school for a long time. The boy's name is Yoshida Haru (Suda Masaki), who was suspended from school on the first day of school because of fighting, but he did not come to school after the punishment was lifted. When they met, they found that Yoshida, who was said to be a fierce and evil man, was actually a very simple big boy. He would be very happy because of others' kindness to him. Out of trust in Shizuku, Yoshida finally returned to school. During this period, young men and women with different personalities, such as Natsume Asako (Ikeda Eriza) and Yamaguchi Kenji (Yamada Yuki), also gathered around them one after another. The youth of boys and girls is destined to be full of blanks... This film is adapted from the manga of the same name by Robiko.
