There's a difference between his smile and hers.
His is from loving a girl so much, that he will do anything for her...even go insane. Most of all, show her how insane he is, hoping, she will love him.
Hers, it's from being so broken and beaten that when she finally meets this one guy, this one spot of happiness that she hasn't ever felt, she falls. Falls so deep into love that she doesn't even care about his insanity.
