Shen Mian has been trapped in her own world for seven years. His social phobia prevented him from going out, answering the phone, or seeing anyone. The 80-square-meter rental house was his entire world. Until a "monster" moved next door - Jiang Ci, a doctor who works in a mental hospital, a taciturn man with eyes as pale as if they had been washed with water.
An alcohol poisoning accident caused Shen Mian and Jiang Ci to intersect. Jiang Ci told him: "You just have a disease, just like a cold and a fever." These words were like a beam of light shining into the dark world that had been dormant for seven years.
But Jiang Ci hides a secret.
The walls of his bedroom are covered with photos of Shen Mian seven years ago. The Shen Mian who wore a white shirt and a bright smile on the university campus, the senior who once reached out to him on a rainy night - and the current Shen Mian who dared not even leave the door, are completely different.
Seven years ago, it was Shen Mian who saved Jiang Ci.
Seven years later, Jiang Ci came to rescue Shen Mian.
But what Jiang Ci didn't say was that he himself was in the abyss. The string of numbers tattooed on his left ankle, the dense scars on the inside of his forearm, and the "object of observation" mentioned in the mysterious phone call... Is he approaching deep sleep out of redemption, or is he hiding something else?
When two similarly scarred souls meet, will they redeem each other, or will they fall into deeper darkness together?
