Since she was young, everyone has stood to reminded her just how lucky she is to live so luxuriously. Little do they know, Minnie doesn't feel lucky at all, not when she's been told she'll be forced to marry a stranger of her father's choice once she turns nineteen. 

Minnie would give up all the money in the world to be able to fall in love with a man of her choosing, but in the world of business; love is for children.

So, when Jimin and Minnie finally get married, they both strive to get what they want. Minnie immediately begins to find a way out of the marriage, all while Jimin starts his quest to turn this marriage into one of a fairytale.

Little do they both not realize, only one of them will truly get what they want.
