Seriously, by posting her name here, u are embarassing her. I
know u don't meant too, but don't u think that her name should be
kept confidential? The "Let-the-world-know-I-like-her" thing u are
doing is really something only actors will do in drama serials. In
real life, often it doesn't work, especially if u are a sec school
student.
Have u asked urself why she is scared of you? It could have been ur
actions came out of the blue. She probably don't know that u have a
crush on her, and think its weird that a "stranger" is doing all
these for her. Besides, at the age u are in, I doubt she really
knows whats a crush anyway.
Just continue to be friends with her. Talk to her like u would with
other guy friends(of course lah, don't add vulgarities). Know her
better before u decide if she's really the gal u like and chase
her. Unlike other forumers, I wouldn't advise u to concentrate on
ur studies, because I believe u are mature enough to know that
studies are for ur future, regardless of what age u are in now.
