In order to find out the truth about his father's disappearance, Su Wan infiltrated the Fu Group and targeted the heir Fu Jin. This man, who is as dangerous as a raging flame, is both a fortress that she must conquer and an abyss that may destroy her.
A contract allows two people to get what they need. He needs her to deal with the family marriage, and she uses it to search for evidence. When the drama turned into a heartbeat, she gradually got lost in his tough defense and late-night vulnerability. This approach, which started out as a calculation, allowed her to touch his truest warmth.
When clues pointed to the deeper secrets of the Fu family, and when the tragedy of another woman ten years ago surfaced, Su Wan discovered that she had already been deeply involved. When the contract expired, she held the evidence, but she was shaken by his pleading eyes.
Truth and love, revenge and redemption. Will this confrontation between the flames and the deep sea eventually burn both of them to ashes, or will they merge into one?
