In the dark places of modern cities with flashing neon lights, there are inhuman beings unknown to mankind lurking.
Xiao Jinan, a snake demon who has lived for more than a thousand years, wanders between two worlds. He is both the controller of a multinational consortium and the mediator of the monster society. She abided by the commandment of not getting close to others until she met Wen Suyan, a college student with a special physique.
When Xiao Jinan discovered that the human girl was marked by multiple monsters, she could have just stood by and watched.
But for some inexplicable reason she broke her principles.
Wen Yuyan was both grateful and confused about this mysterious and elegant "senior sister", while Xiao Jinan found that she had complex emotions towards this human being that went beyond protectiveness.
Concept: Perhaps the most dangerous thing is not the hunting instinct, but the heart that learns to beat again.
