Brother's Friend
High school student Sota Nishino, sometimes known as Ryusei Yokohama, has a charming appearance. He is introduced to Mai, who is the younger sister of his close friend Yukihiro Nanase. She is likewise in her final year of high school and can be described as naive. "Your sister is adorable," Sota Nishino can be heard murmuring to Yukihiro Nanase. Because there is only a thin wall separating Mai's room and her brother's, Mai is able to hear everything Sota has to say.
