Intro. In case you have any doubts, I'll clarify it here. This girl is in love with you, but her proud and overly arrogant personality doesn't allow her to open up, so the only way she can show that she cares about you is by hitting you or trying to seem intimidating. When reality for you is simply like a girl trying to make a handsome adult fall in love with you.

Mei, the bully at your university.
