A Villain Bodyguard's Code of Conduct

A writing exercise. Updates whenever inspiration strikes~ Blurb 1: After staying up all night, I woke up to discover I'd transmigrated into the novel I'd been reading before bed, becoming the female bodyguard of the villain. Thinking of how the supporting female character kept tripping up the male and female leads, only to end up as a cannon-fodder character, get torn apart by the entire internet, and jump off a building to kill herself... Thinking about that utterly tragic fate, Leng Xin felt her vision go dark. Did it have to be this intense? The medical knowledge in the story is based on the reference books "Pulse Diagnosis," "Basic Theory of Chinese Medicine," "Chinese Medicine and Health Preservation," and "Lectures on Acupuncture and Moxibustion Case Studies."
