Gun Zenkai visited the Daigaku-ryo where his younger brother Keiichiro lived. He met his younger brother for the first time in three years, and he was completely choked.
Keiichiro, who became his younger brother after his parents remarried 11 years ago, doesn't seem to like him. Even though it's been a long time, his attitude is unfriendly and blunt.
However, Zenkai wanted to use this as an opportunity to deepen his relationship as a brother, and Keiichiro left the dormitory due to an accident.
I know he doesn't like me, but when Zenkai suggested to live together, Keiichiro suddenly got angry and said, "The one I've always liked is my older brother!".
