Cheng Qi, a poor student at the Academy of Fine Arts, rents Room 404 of Qinghuai Apartment in order to save money, and is forced to share the apartment with Xie Lin, the owner of an antique shop. The other person's other identity turns out to be a shady person in Fengdu, and he also hides an obsession that spans seven generations.
The psychic physique collides with the thousand-year soul chain, and in a series of strange puzzles, the true rules of "haunted house sharing" are revealed - not to suppress ghosts, but to suppress his madness that has been rampant for thousands of years.
The wound on Xie Lin's heart is the scar of reincarnation, and Cheng Qi's blood is the only medicine.
——"You risk your life to calm my soul, and I will stir up hell to accompany you crazy."
Intention: Even if your destiny is full of farewell, you must change your destiny for love.
