Most Helpful Guy
Most Helpful Girl
He misunderstood what you meant by helping you with your homework.
You actually wanted help with your homework, he took it the wrong way and didn't think you actually wanted him to help you and saw it as, hook up with him.
I think he is mean because he is confused and mad about the situation. He probably likes you and knows he messed up and doesn't know how to express his feelings.
All in all he is only looking for one thing-- sex.
