I think the secret will be - she was in a coma for 10 years; is still in school, but technically 22 or something. Even if it's a manga - without a giant time leap, I can't really root for them. And the girl is way to physically developed to be a child. And her looks make me blush. Even mentally sometimes she seems the eldest.

This looks great, but Caitlyn should be the tall one. Still really like it though :)
