Kyouya Yaguchi

A man who had once been in a close relationship with Sayu Ogiwara reunites with her at their part-time job. He tries to take advantage of their past connection to make advances toward Sayu at Yoshida’s house. However, he is sternly reprimanded by Yoshida and receives a slap from Asami Yūki, who make him swear not to lay a hand on Sayu and not to speak of their past relationship. From then on, he adopts a cooperative attitude toward Sayu, including when Issa Ogiwara comes to the part-time workplace.
