^ I really like it when she wears her hair straight too. It's become so rare nowadays that I get extremely excited when I see it
Her straight hair looks so soft and silky in the pic below:
I'm a fan of all her hairstyles. When it's wavy/curly and let down, she's channeling all kinds of sexy. When it's straight, she emits schoolgirl or girl-next-door charms. When it's curly and tied up in a bun or ponytail, I just want to marry her and bring her home (it's the housewifey image). And finally, with side-swept bangs or no bangs, she reminds me of some K-pop star.
Now I'm wondering if she'll update her image yet again when her second solo single rolls around.
