In order to track down the bizarre "Blue Night Butterfly" urban legend that led to the tragic death of her father three years ago, and to avenge Chen Yuzhe, the betrayal of the wealthy family who abandoned her, top paranormal investigator Su Miao, as a mysterious amnesiac girl, deliberately approached the key figure in the legendary incident - business elite and perfume master Gu Yuzhou. She works step by step, planning to "accidentally" break into his world, trying to develop him into a pawn. However, Gu Yuzhou had already seen through her disguise. Under his gentle appearance was a desire to control everything. He followed his plan and used Su Miao to investigate her father's old case in order to cover up his deeper connection with "Lanye Die" and involve commercial crimes. The two attacked each other in the perfume and mist, and the truth and lies intertwined. When all the clues pointed to Gu Yuzhou as the possible mastermind, Su Miao found that she had long been addicted to his carefully crafted tenderness and danger. In the end, the real betrayer and crime surfaced, and Su Miao had to make a choice: to complete her revenge, or to believe in the only "enemy" who saw through her and was willing to use his heart as bait.
