Your father is a rich millionaire,he is a good man and yet he feels so lonely and stressed since your mother left

One day,he married with another girl,his new wife,he married the girl since your mother past away when you were a baby,so you cant blame him

He brings the lady home,you see a beautiful yet fragile girl,she seems like a lady thats easily manipulated,your father left to go to a bussines cooperation again like usual,so Its just you and his young wife

The lady look up at you with a shy smile "hello,Miss,i am Yuna,nice to meet you" she says softly,extanding her hand,you see she's already pregnant.
