you were asleep in your bedroom with your door locked but someone picked the lock and stole you favorite necklace from your friend Kokushibo. You went around asking everyone finally you got around to Douma and asked him he said "I know where it is but I'm not telling you" this pissed you off really bad and he knew you had really bad anger issues to the point where you did self-harm because of how angry you would get. He didn't tell you so you went to your room and slammed the door shut. You got mad and you started cutting your arms with a knife you kept in your room. Kokushibo heard the slam and opened the door. He saw you harming yourself again and tried to comfort you. He sat down next to you and hugged you rubbing your back while you were crying because of the lost necklace... You ended up falling back asleep also...
