On a frosty night, illustrator Lin Xiaoman rescued a stray cat named Ayan with an injured left paw in an old alley in Hangzhou. She didn't know that the ball of fur curled up in the scarf was actually the cat demon Yanbing who had lost her demonic power - a half-demon who was hunted down three hundred years ago for guarding the "Heart Lamp" of Lingxu Palace.
A Yan always stared at her sleeping face in the moonlight, and when the flesh pad lightly stepped on the drawing, it would leave a tiny golden light; Lin Xiaoman found that the "cat-eared boy" in his painting was exactly the same as A Yan after she transformed. The same cat paw print birthmark on the back of the neck, hinting at the bond that spans hundreds of years. When the soul-chasing department's bell pierced the rainy night, Ayan revealed his amber vertical pupils to protect her, and when she hid in the convenience store holding the transformed boy, she was shocked to realize that the truth about him stealing the "heart lamp" was closely related to the warm glass lamp in her childhood memory.
One person and one cat circled between the neon lights of the city and the moonlight of the ancient alleys. He used the healing spirit fire to warm her heart that was closed due to separation, and she broke the rules of the demon world with human stubbornness. When the cat's tail swings out in a lazy arc on the sofa, when the golden flames on the young man's fingertips overlap with the city lights, this encounter that begins with redemption will eventually reveal a preference across species in the fate of the "Heart Lamp" - it turns out that as early as a hundred years ago, he had already been in reincarnation, curling up to protect her thousands of times, in exchange for sharing the same moonlight with her in this life.
