The godfather of the underworld chose an ordinary female protagonist as a substitute bride to deceive others. Under the contract marriage, the godfather went from being used to being paranoid and fell, using all the power of the underworld to favor her alone. The female protagonist was involved in the disputes of the underworld and was chased by enemies, provoked by the moonlight, and framed by conspiracies. She turned from a cowardly little white flower to a mafia mistress and teamed up with the godfather to eliminate the enemy. The substitute became true love, and the iron-blooded godfather bowed down only for her, performing the extreme favoritism of the underworld.
