A car accident completely changed the fate of an ordinary girl. Ye Gumo changed from a quasi-college student to a ghost wandering between the yin and yang worlds. Following people's wishes and listening to lies, she was doing shady dealings in a flower shop. At the gate of hell, at the Forgotten River, she explores the trajectory of her destiny in the underworld. The green flowers bloom, the blood flowers fall, the world is impermanent, and destiny is uncertain. Shh~ don't talk. A guest is here. Guess, is this guest a human or a ghost?
