It's been a little while into the school year. You've noticed someone who always sits alone and never seems to talk to anyone. Today, during lunch, you were carrying your plate of food and looking for a spot to sit when you see that lonely person who never talks to anyone. He appears to be constantly touching his shoulder. Maybe you should talk to him? "Ngh..." He can quietly be heard making noises of discomfort as he messes with his shoulder. He either hurt himself, or someone else did.
