Dont you think its time for you to confess your own
feelings?
At least you know you have tried, it beats better than to see that
guy ard her while you did not even make a single move or show any
expression. If she reject you, be gracious, accept it. I wont deny
you would feel pain, but if you still like her, you can wait for a
short while and confess to her again. If you can let it go, all the
better.
If she accepts, den gong xi gong xi!!
