Tang Shiyue, a corporate wage slave and the heroine, accidentally rescues He Chenye, a cat demon and the hero, who has been trapped by a villainous snake demon for three years. The two get caught up in a series of farcical mishaps, and through their repeated push-and-pull and mutual testing, they gradually realize that they are each other’s only reliable partner. But behind their seemingly coincidental meeting lies a century-old feud of revenge between Shiyue’s family and the snake demon. Shiyue and Chenye join forces and enlist in the “Human Order Bureau,” led by the scheming fox boss Su Qing, forming a detective squad. As Shiyue and Chenye grow closer, Su Qing launches his own campaign to compete for her and “steal her away.” As the investigation progresses, the squad pieces together the clues, and a shocking secret of trust, betrayal, and a century-old vendetta comes to light. They discover that the jade bangle passed down through Shiyue’s family is the key to solving the whole mystery. As the New Year bells ring and the rare alignment of six stars draws near, the snake demon’s plan gradually comes into view. Shiyue and Chenye step into the unknown side by side. Can they protect the bond that brought them together?
