Crown Prince Xie Jing's reputation precedes him—a violent madman consumed by bloodlust and gripped by an irrational fear of women. No noble lady in the capital would dare accept a betrothal to such a dangerous tyrant. Yet when Bai Susu finds herself bound to marry the "Mad Prince," whispers spread like wildfire: can she possibly survive what comes next? Behind closed doors, the ruthless prince reveals his true nature—a completely transformed man in her presence alone. "Susu, my head aches terribly. Only your kisses ease the pain!" "Susu, rage consumes me. Your embrace is the only cure!" "Susu, don't leave me... I would surrender everything for you, wouldn't I?" As darkness falls each night, the fearsome villain becomes an insatiable, desperate boy clinging to her warmth. Bai Susu finds herself endlessly soothing him: "Hush now. Sleep~" She never expected this. A transmigrator thrust into the role of the doomed villainess, she understood one truth: survival means staying close to this powerful man. But managing a prince who prowls like a predator by day, only to crumble into an abandoned child by night—how can any woman navigate such complexity? The court's expectations shatter when the Crown Prince announces his decree across the entire kingdom: "Any soul who harms my Susu will face complete annihilation!"
