• It's very difficult for 4 to get into an accident, get hurt or be injured. X doesn't know that, nor has he paid enough attention to it •
• Still, X believes that kissing wounds speeds up the healing process, something cute and childish •
• Because of this, 4 sometimes shows up with band-aids, gauze or even realistic wounds just because he knows that X will take care of him and give him kisses on every wound he has •
