Moon Yoonah is used to have everything her way. 

The 8-year-old girl is the future heiress of the empire of 2 families: a korean one and a british one.

As her parents had an arranged wedding, the couple got divorced once they fullfilled their obligation to produce a baby.

Despite of that, Yoonah was raised watching  her parents keeping a civil relationship.

Little Yoonah is more mature than most adults around her and she is a mini version of her mother Moon Byul-yi when it comes to fashion and style.

One day, Yoonah uses the office of Moon corp to have an interview with 200 women and these females have no idea that the child is about to choose a candidate to be the mother of her future brother.

This is how Kim Yongsun finds herself being offered the weirdest job of her not so long life.
