Jiang Li, an energetic, super-strong manic patient, transmigrated into a submissive-girl angst novel she had vented about. Her core rule is if she's unhappy, no one else will have it easy. She sleeps with the King of Hell, beats up villains, and talks back to her entire family. In the end, the villain is abused to the point of doubting life itself, and even the Regent of the capital—decisive, ruthless, and nicknamed the Living King of Hell—is charmed by her until he has no temper left at all.
