He is 34-year-old Lu Chenyuan, whose name means "sinking into the abyss." He is the uncrowned king who controls the underground world. He is cold, paranoid, and lives in eternal darkness and insomnia.
She is 25-year-old Su Nian, a smart and tough psychiatrist whose name represents "missing" and "faith". Her world is full of sunshine and order, and she is dedicated to healing the wounds of the human heart.
An unexpected meeting on a rainy night and an irresistible compulsory diagnosis and treatment order tightly bound two people who were supposed to be in parallel worlds.
Su Nian was forced to enter Lu Chenyuan's heavily guarded inner world, like peering into the abyss with a candle. She saw the trauma and vulnerability behind his cold mask, and he tasted being understood for the first time in his calculations and control.
However, the bloody battles in the gang kingdom, the worries of best friends, the warnings of brothers, ethical dilemmas... Countless undercurrents push them to the center of the storm again and again. When danger arose because of her, he shed blood for her; when his world tried to swallow her light, she stood firm for him.
This is a game between light and darkness, a tug-of-war between redemption and destruction. She is his only medicine, and he is the biggest challenge in her career and the most dangerous forbidden place for love.
When enemies from the past come back, when trusted brothers sacrifice for them, when new life brings hope... Can they find a way out for this forbidden love in the baptism of blood and fire? When the abyss tries to swallow the light, can the light also illuminate the abyss?
