The grandson of the antique dealer and the beggar princess are married. The contract period is 2 years to promote the interests of each person.

Captain, a promising naval officer. He is the grandson of an antiques dealer who is always looked down on because of his lowly pedigree even when he achieves resounding success. Bastian Clausitz needs a stepping stone to success and revenge.

A fallen aristocrat is only a glory of the past. Despite carrying royal blood, the princess still has to make a living by selling her daily labor. Odette von Dessen needed money to start a new life.

Both sides consider this to be a promising transaction. Until there is damage no one can foresee.

"I messed up the things that are most important to me, so it's only fair for you to lose the things that matter most. Isn't that right?"

Bastian decided to hold her pontoon responsible for the enormous damage. Hate and resentment, nostalgia, including this damn woman.

Because of the perfect ending, everything burned white.
