Kyoutaro Ichikawa may seem like an average middle school student on the outside, but deep down he harbors a desire for violence. His ultimate target is none other than Anna Yamada, the class idol, whom he has long envied. While studying alone in his favorite library, Ichikawa accidentally encounters Yamada, who comes to indulge in her sweet treats in secret. Through their interactions, Ichikawa discovers that Yamada is rather dim-witted and teases her mercilessly due to her flustered responses. Despite this, the two develop a heartfelt bond through daily conversations. As time passes, Ichikawa may come to realize that his murderous urges have evolved into something entirely different.
