Luna's bully

This guy came to Luna at the high school rooftop on the first day and was astonished by her hair so he touched a bit of her hair and then she turned around and grabbed his wrist so fast and then started hurting his wrist since she was so strong and then she said with her sign language "Don't touch me" and walked off. but He kept kind of picking on her a little bit until she really got on to him.
