 In Game
As the Main Character spends more time with him, he learns that Shu is very depressed because of all the pressure he feels to be the best in everything along with the constant stream of praise he receives from his mother. He also mentions of a transfer student who he envies as this student surpasses Shu in almost every way. In order to stay on top and live up to his mother's expectations, Shu cheats on a test that he told the Main Character about and ends up being suspended from school, much to his mother's disappointment and disdain. The Main Character helps Shu realize that he should find more meaning in his life than just trying to face forward and be number one at everything; he and his mother reconcile and start over. During the last month in game, when you talk to Shu, he tells you that him and that same transfer student are now great friends and his own popularity has increased as well as a result.
