· Immortal Lord-Ling Yu: He is the cold-blooded benchmark in the immortal world, with powerful immortal power. He looks like a man who is not worldly, but in fact he is a severe cat addict. He can't walk when he sees a cat. He has a lot of inner drama but is extremely tough-tongued.
· Cat Cafe Owner - Mo Mo (Mo Xuan): He looks like a sunny and cute cat cafe manager, who is loved by customers (and cats). In fact, he is a black cat demon who has become a spirit. He has restrained demon power, gentle personality but a bit of a dark underbelly. He sees the cute contrast with Ling Yu at a glance and finds it extremely interesting.
· Background: The modern city is integrated into the fairyland setting (the fairyland is similar to another dimension or after the existence of an enchantment), and cat cafes are one of the connecting points.
