Based on 10 things I hate about you, but in a wlw version.

1–Your older sister could only date if "you" were dating too.

2–You weren't dating anyone—by choice and because no one ever got close.

— Sadie... why are you doing this?

— Doing what? — she said, her heart racing.

— Treating me... like I'm special.

She swallowed hard; this wasn't part of the agreement. But it was in her heart

— Because... you are. — Sadie whispered.
