The princess who lost her favor was arrogant

She, the assassin of the mysterious organization, had transmigrated to become the third princess consort of the Underworld King Dynasty. On the day of their wedding, the groom had rejected her at the door. The cold and aloof her covered her mouth and smiled before turning around and leaving. Since he was unwilling to marry her, she did not care about it either.

He, the Third Prince of the Nether King Dynasty, did not love her. He was ruthless and bloodthirsty. He tried every means to torture her. He did not expect her every frown and smile to be deeply engraved in his mind.

The love that was blinded by hatred, until it was lost, would he be able to find her? Pick up the love between them again?

When the bloodthirsty him met the cold her, where would the infatuation between the two go?
