Lin Xuan transmigrates into an urban low-martial arts novel, becoming the hot-tempered villain destined to be wiped out by the returning protagonist. Framed by his illegitimate brother and disowned by his father, he is forced to marry Su Qingge, the vegetative granddaughter of a powerful family, as a substitute groom. However, Lin Xuan awakens the 'Crazy Clingy' System, which rewards him with points and skills for maintaining physical contact with high-luck individuals.

Seeing the comatose heroine as the perfect source of luck and protection, he enthusiastically accepts the marriage, vowing to care for her forever. While Lin Xuan plots to hide behind the protagonist's sister and live a carefree life, Su Qingge remains fully conscious within her paralyzed body, screaming internally in despair until his warm touch offers her the first glimmer of hope in her living hell. Now, the supposed villain must navigate family conspiracies and the impending return of the main protagonist, all while sticking close to his sleeping wife to power up his new abilities.
