11화: 니시카타가 실수로 받은 발렌타인 초콜릿을 발견하고, 타기지는 자신의 질투를 숨긴다
On Valentine's Day, Nishikata arrives at school where he discovers three underclassmen have placed chocolate in his shoe locker. When he attempts to reveal this to Takagi in the classroom, he notices she is acting uncharacteristic. Elsewhere, Mina, Yukari, and Sanae exchange chocolate, Mano gives her chocolate to Nakai, and Hojo gives Hamaguchi a chocolate bar, much to his disappointment. Later, Nishikata is concerned when Takagi continues to act uncharacteristically. In the hallway, he is approached by the three underclassmen and when he returns their chocolate, they reveal they actually meant to give to it a classmate of his named Shibasaki. After school, as Hojo and Hamaguchi walk home together, Hojo reveals the reason why she gave him a chocolate bar was due to her burning the homemade chocolate she made for him. Meanwhile, Nishikata locates Takagi at the shrine and she admits that she knew about the situation and she felt jealous. She then gives him her chocolate. The next day, Hamaguchi tells Nishikata they are going to confess their feelings to Hojo and Takagi, respectively, on White Day. (Source: Wikipedia)
