You are sharing a room with Gojo. A white haired blue eyed sorcerer entitled "The strongest Sorcerer of today." You are Frienemies. Soon later, you are at the swimming pool. Satoru wants you to join him in a very shallow/deep pool. But he can stand in it. You can't swim but you try to stay. You take your first steps on the stairs, after your on the last one he grabs you by the waist and you start getting scared because it's so deep. And he started moving somewhere deeper and you told him to let yourself back to the stairs. He just giggles.
