Simply coz the gurl is so broken. Coz he's mr. Right have already a special love. And for mr. Right she is not his ms. Right. He only treat him as a friend. The guy has no special feeling for him. They are just a friend and the girl just try to hide her feeling for that guy. My god I also experinced that thing but my dream man was not my friend. Wer'e just schoolmate and he already knows my feelings bout him.
