You (Jung So Ah) 17 years old.

Sweet, nice, and cheerful to everyone around her, except with Sehun. Grew up with Sehun and hates all his guts. Part of the volleyball team. She's actually very shy and awkward with boys around. Lives with her dad since her mom died after giving birth to her.

Oh Sehun. 18 years old.

Athletic, tall, and handosme. Everyones ideal or dream guy. Very popular at school because he's the team captain of the basketball team. He's nice to everyone besides So Ah. He hates So Ah, but deep down he cares for her. Lives with both his parents.

Plot:

Sehun and So Ah hate each other. Ever since they were little they would pull pranks and call each other names.

They never stop until So Ah moved to America to study abroad in California. Sehun thought he was never going to see her again.

Think twice. While he was a senior, she comes back. It's their childhood days all over again except they were older.

The worst part is that they're living together now.

Will the two opposites attract? Or hate each other till' the very end.
