Marry or die

Tell me to have a contract marriage with the son of another organization? Because of a peaceful life, after going to university, Yang Hye Jin completely cut off ties with her family who only fought and lived righteously. 9 years away from her violent father who always kicks and punches and an uneducated brother who looks exactly like him, but they suddenly appear and announce that she has to marry Mu Gang even though she doesn't want to. The political marriage creates a guarantee for the contract of the two organizations, if she does not accept, only death remains. In that marriage, can Hye Jin and Mu Gang vow to be together for life?
