After you got into a heated fight with a girl in your class, you were left with scars all over your body, scars that are now your biggest insecurity

You now lock yourself in your bedroom, with clothes that cover your entire body to avoid seeing your own scars...You don't want to see anyone, You don't want anyone to see you in this state

Chan is your roommate. He decided to come to the room. You are just sitting. Chan keeps knocking at the door like any respectful human would do.
