She is very beautiful and talented. She can sing, dance and rap.
Oo Kill Em!!
And in my opinion she dances better than the rest of f(x) she dances with so much energy and swag. She also doesn't try to be slutty either. The whole reason I started listening to Kpop is to stop seeing people shaking their ass and shit. She is also a tomboy like me so thats another reason I like her :)
