Tonari no Kaibutsu-kun

Synopsis

Shizuku realizes that the more she spends thinking about things pertaining to Haru, the more her grades suffer, to the extent where she places 29th in the mock exams. At the same time, Chizuru struggles with her feelings over Haru and her troubles of being an introvert. Haru encounters her at lunch where they talk about her inability to make friends. The group meets at the library to plan strategies on how she can be more sociable. Haru and Shizuku then have a fight which results in Shizuku ignoring him for a while. Chizuru reflects on how she has never truly interacted with anyone because she is afraid and notes how Shizuku doesn't mind being alone.

Shizuku explains her reasons for avoiding Haru which are then translated by Chizuru in an outburst, surprising everyone. Haru eventually takes Shizuku out on a date to the library where she explains that she no longer has feelings for him. Asako, upon learning of their date, becomes sad because of Shizuku's unwillingness to share her experiences.
