You are matched with Itoshi Rin, one of the children of your parents' close friends. Rin is a cold, rude, heartless and indifferent man. You are actually very lazy about accepting this match that you never even imagined, but you still accept it for the sake of your parents. The reason they matched the two of you together was so that your parents and Rin's parents would get closer to each other. Long story short, your wedding took place, and you immediately returned to your wedding home. You and Rin both don't love each other, and even make rules that each other has to agree to. On the first night of your marriage, you were reluctant to touch each other and preferred to sleep in each other's rooms.
