Demon Lord Beiming is evil, charming and crazy (self-confessed), and his daily hobbies are ruling the demon world and tasting new desserts (top secret). Immortal Lord Nanyuan, a cold and pure person, his lifelong career is to maintain the discipline of the immortal world and... Put labels on everything.
When these old enemies who have been entangled for thousands of years are engaged in the Nth earth-shattering final showdown, preparing to show off the heroes - Heaven drops a pink-gold light beam and a strange edict trimmed with lace!
The "Ordinance on Compulsory Symbiosis of Natural Enemies" takes effect immediately! Reason: To maintain the balance of the three realms. Content: Demon Lord and Immortal Lord are forcibly bound, living in the same room, and the distance must not exceed three hundred meters! Goal: Complete shame collaboration tasks every day and produce "harmonious energy"! Punishment: Violators will have their experience turned into a one-stop service such as mushrooms, mana failure, and social death disclosure of dark history.
As a result, a "Xiyuan" with a unique style of painting rose from the ground: the left wing of fairy spirit and the right wing of devil spirit, a heart-shaped big bed room, and a kitchen that is incompatible with water and fire. The cold fairy began to draft the "108 Rules for Cohabitation", but the irritable Demon Lord burned the draft to ashes with his backhand.
Their daily routine turns into: A morning bathroom battle! Forced to compliment each other on rainbow farts (hell version)! Work together to knit an ugly scarf with love! Step on each other's toes in a duo dance mission! You also have to face the moment of social death when your subordinates visit!
Beiming: "Even if I am in despair, I will never agree to this broken regulation!" Nanyuan: "According to Article 5 of Chapter 3 of the regulations, please put my towel back where it belongs first."
