On the day Chen Mo moved into Apartment 404, he realized something was wrong with the place.
Seven tenants, seven sins, seven deaths.
The gentle nurse Lin Wan is an "Angel of Death." Countless souls have fallen beneath boxer Zhou Ye's fists. Influencer Su Xiao drove an innocent girl to her death through cyberbullying. Rich second-generation heir Qian Duoduo fled the scene of a fatal hit-and-run. Professor Zhao, a psychologist, conducted illegal experiments. The elderly housekeeper Wu murdered her husband. And Chen Mo himself has prosopagnosia: he can never clearly see anyone's face.
As the tenants die one by one, Chen Mo discovers that their scars are all in the same place, their scents all seem familiar to him, and their memories are all in his mind...
They are all him.
Room 404 is his subconscious. The seven personalities are his other selves. And the time experiment, which has lasted 30 years and repeated a thousand times, has only one purpose: to create the "perfect human."
But perfection comes at the cost of humanity.
When Chen Mo finally confronts the deepest truth and the "self" who designed it all, he must make one final choice:
Become a perfect god, or a complete human being?
