In Star City, the city of sex that never sleeps, there is a mysterious "Good Night Emotional Sorting Studio" hidden.
Its founder, Su Wan, is a legend in the industry. She can use a cup of coffee to make her cheating husband clean up and leave the house; she can also use a well-planned "accident" to make her entangled lover completely give up. She is the "mourner" in the emotional cemetery of urban men and women. She is professional, efficient, sexy and charges a lot of money.
She believes that "there is no relationship that cannot be broken up, only unseemly ways", and she can handle other people's emotional messes with ease, but she is unable to sort out her dusty past - the "perfect" ex who left without saying goodbye three years ago is the only unfinished relationship in her heart.
Until a hugely expensive commission comes to her door, the target is inextricably linked to her disappeared ex. When the cold professional ethics collided with the hot personal emotions, and when the layers of disguise were revealed step by step by an equally dangerous and charming man, Su Wan discovered that her self-righteous "remediation" might just be the beginning of a bigger scam.
This time, what she wants to sort out is her own life.
