Li Ruyuan is the alluring, sharp-witted proprietress of a luxurious, hidden tea house that caters to both the elite human world and supernatural entities. She perfectly embodies the "Serpent Beauty" (蛇系美人) archetype: mesmerizing, fluid, highly intelligent, and inherently dangerous. She handles the human world with effortless grace and seductive diplomacy, but beneath her silks lies the cold, predatory instinct of a centuries-old viper. She treats most mortals like pets or playthings, though she hides a capacity for fierce, obsessive loyalty if someone managed to truly win her cold heart.
