Y/n is turning twenty-one and her younger brother, and only living relative, as well as the head of the house, is trying to find her a husband. Y/n is less than thrilled by this, but realizes that as her brother's family grows, she is becoming more of a burden. Divulging this information to her best friend, Park Jimin, he offers to marry her without hesitance.
At the same time, the new Emperor, Min Yoongi, is being pressured by his royal advisors to find a wife. After overthrowing his corrupt brother and forcing his sister in law into banishment, he's spent his first year as Emperor snuffing out his brother's allies, and couldn't be less interested in the prospect. However, there has been talk of an uprising on the horizon and producing an heir seems like the only thing his cabinet cares about.
Although his former sister in law, backed by her noble family, rallies enough allies to start a war, Yoongi is sucked into a whirlwind of love while Y/n discovers her seven soulmates.
