Admirer

Got a friend, do not know whether he will change to admirer or not...
I am occupied with another guy, and, I'm not that kind of girl who wants to hurt guys...
Tell me what to do? To prevent he will not experience what I experienced from the "another guy"?
The "another guy" does not want me, and there are guys who want to make me happy...

And if I tell the "another guy", he sure will very happy and ask me to try accept the friend!!!

Ming ming, you very bad T.T
