In the abyss of emotional numbness, Lindy was led to a secret underground emotional auction house. Here, memories are refined into perfume, and both happiness and heartbreak can be priced. She bought a piece of "happiness" at a high price, but when the fragrance filled the air, she frequently flashed back memory fragments of a strange woman - sunshine, a white dress, and a man's gentle profile.
That man is Pei Huan, who appears to be a calm psychiatrist, but secretly is the host of the auction house. When Lindy discovered that the happiness he bought actually came from his late ex-girlfriend Su Wan; when Pei Huan recognized that the emotionally greedy woman in front of him could always trigger his buried pain, the two were bound by a perfume called "Midnight Heartbreak".
Memories overlap, and the truth gradually emerges like the top note of perfume: Su Wan's "accident" hides a lie, and the price of emotional trading is the devouring of the soul. They got closer amid temptation and pull, and saw their true selves in each other's wounds. When the final recipe for "Midnight Heartbreak" emerges, what is needed is not obsession, but the courage to let go of the past.
This is a transaction about redemption, exchanging sincerity for sincerity, so that the brokenness of midnight will finally open up new possibilities in the morning light.
