Shunji Fujii (voiced by Takumi Hachioji) lost his mother at a young age, which filled him with admiration for older women. One day, by chance, Shunji met his English teacher, Yangna Tachibana (voiced by Yako Matsuda), on the rooftop of his school. Tachibana's gentle demeanor deeply captivated Shunji, and he found himself falling in love with her. However, Shunji knew that there could be no future between him and his teacher, so he channeled his frustration into social events. At one such event, Shunji met a girl named Rui (voiced by Manami Ito). On that day, Rui gave her first time to Shunji. Later, Shunji's father informed him that he was going to remarry, and the new wife would bring her two daughters to live in Shunji's home. To Shunji's surprise, the two girls turned out to be none other than Tachibana and Rui.
