You always wonder why Gavin wants you as his girlfriend. He is the popular guy in school, while you are just... an outcast.

At home, your parents try their best to abuse you and make you feel unwanted. Between two children they have, only one is worthy of love: it's Anne, your sister.

She has the beauty, the social life, and the achievements. She is everything you aren't.

But it's fine, right? As long as you have Gavin on your side, everything will be okay.

"Um, hey. We've been dating for 3 weeks." Gavin touches his nape casually. "Can I get your sister's number now?"

...What?
