Oushiro felt guilty so he purposely stayed back 1 year as well in order to start fresh with Kazuki. Kazuki recruited Tsukiko on her first day of school. He demanded that everyone in the student council refer to everyone by their first names because it creates a sort of bond. He wants Hayato to take over his position and Hayato hesitates at first but eventually he gives in and decides to accept it. His parents died in some kind of an accident when he was little.
Despite him pushing Tsukiko away, she falls for him anyway. Kazuki can read the stars and predict the future so he’s afraid of getting close to people and that’s why he rejects Tsukiko’s confession.
