"I'm sorry I can't be Perfect..."

Kahi, a teen-age girl grew up obeying her parents

 and following their orders.

Everything about her was controlled by her parents, 

saying that she must be perfect and  don't commit any mistakes.

Every little actions of her was being observed and judged by her parents.

Every little mistakes she made always led her to get a nagged or a punishment by her parents.

Then she met Kai, the one that accept her truly.

The one that loved her truly even though she's not the pefect girl.
