A man marries a woman with the ulterior motive of staying close to his wife’s younger sister, a sister who feigns innocence while playing games with her, and parents who see her as an unwanted burden. This is the tough reality for Han Yi Ju. After witnessing a shocking event, she is hit by a car while fleeing from shocking reality. Even on the brink of life and death, her genuine desire is for vengeance against those who made her life miserable.

Thus unfolds a dramatic tale of love, secrecy, and payback as Yi Ju, ready to risk everything for vengeance, and Do Guk, harbouring affection for Yi Ju, enter into a contractual marriage.
