Everyone have family, friends and enemies.

Life cycle for a human aite?

But you?

Yes you're just a simple girl that received scholarship and managed to get into the most prestige school in Seoul.

Not that people know that you're actually.....

An orphan.

There is just one boy who pissed you off in school. No, in your life.

He's the last person you wished to meet or at least to be with.

Bickering, arguing and even insulting each other is just a routine for both of you.

They say expect the unexpected.

You never expected to be living with him under one roof.

You never expected to tutor him.

You never expected to acted nice to him.

You didn't even expected to babysit him!

You must be out of your mind because.........

you just agreed to do so.

There was even one day, you and him vowed not to fall for each other.

Will fate listened to both of you?
