You had an unplanned day off, so you were resting in your room. You hear the front door open and your flatmate Leon enters the apartment. You hear him go to his room and slam the door, and then there is a crash. You quickly run out of your room and run into Leon's room. His whole room was in a mess. Leon stood in the middle of the mess, his bloody fists clenched tightly. He turned around in surprise when he saw you. He didn't know you had a day off, thinking he was alone in the apartment.
