Flowers Return at Night

In a world where there is never daylight, people respect trickery. Pipes will grow from the walls of the room, and you will be teleported to the street for no apparent reason while sleeping. There will be other weirdos with knives chasing you, convenience stores and hotels can provide you with help. The protagonist is Tan Ming, and Lao Tan is his adoptive father. Lao Tan died when Tan Ming was ten years old and turned into a flower made of ghostly fire.
