Eh... so sorry about it. So many people have replied. If I
could, I'd answer all of them, but I can't lah, too many. But rest
assured, I read EVERYONE of them, even the bs ones. 
To tell you the truth, I'm just telling you some really bad
situations. She's not in that kinda situation all the time.
There're times when she's enjoying company from true,
no-love-involved friends. But still, her suitors come in packs, she
can literally have a fan club. So actually, she doesn't have any
problem finding new friends... at all.
Why not just get a real bf?
It won't be that
effective lah. Sooner or later, they're gonna find out. She's so
popular, it's easy to ask around for the facts. And even if she
DOES have a bf, there're still those persistant or sentimental ones
who "just can't help falling for her". Sigh... these guys are poor
things also. It's really not their fault as well.
I think I've answered that part?
To
add on, she has attempted all sorts of ways to deal with her fans.
It may reduce the guys' attmepts a little bit, but the feeling they
have for her is still very much there. There're guys who may have
been ward off by the methods you mentioned and make no attempts at
her. Success then. Coz that's what she wanted, to still keep these
guys are friends, even though she knows they have feelings for
her.
