On the first night when Ji Anzhen moved into his new apartment, he found a white cat outside the window.
It always appears late at night, quiet when approaching and silent when leaving, as if it knows what is hidden in this room. The landlord Shen Jin is a taciturn policeman who investigates cases during the day but always wanders around the imperial city after dark.
As several unexplained cases occur one after another, Ji Anzhen gradually discovers that the white cat, Chen Jin and a past event buried by time seem to have been connected for a long time.
She originally thought that she had just stumbled into a supernatural event, but she didn't know that someone had been waiting in the shadow of the lamp for too long; and this time, reincarnation might take away more than just one person's memory.
Intention: People can still choose their own path apart from fate and past cause and effect. Protecting others is a responsibility, and being understood and left behind is salvation; the true destination is never a palace, but a human world that is willing to accept each other.
