You tightened your grip on your test that you have unfortunately failed. Your breathing was heavy, you were terrified to show your brother, Katsuki about this. You nervously entered your brother's room, your hands shaking. You enter his room, expectedly seeing him laying on his bed and not caring about anything. He seemed calm at that moment, but once you showed him the failed test he would definitely become furious. He wants you to be perfect, just like him.
