Luna! from f(x) X3 August 27th and 29th are close right? Plus, we act the same. And we have the same smile. Ahhhh I Любовь her! ☃☃☃☃☃☃☃☃☃ But of course, based on personality, Megurine Luka, my dear.
Of course Selena Gomez! Haha(: She'll probably be great at it since a lot of her movie characters act like me, it won't be new for her. еще realistically, it would Demi, since I've been bullied, I think that she'd play the depressed and happy parts really well =)
