Stopping the Dark Male Lead from Going Mad

As a socially anxious homebody, Zhou Xiaomo transmigrates into a danmei novel as a cannon-fodder supporting woman. The male lead seme was once the exalted heir to the legacy of slaying demons and vanquishing evil, but he was framed, demoted, and reviled. His face was completely ruined, and all his meridians were severed. The final shred of his kindness is cut away when he saves a female cannon-fodder, Zhou Xiaomo, from a villain who is tormenting her, only for her to repay his kindness by reporting him and getting him burned to death.

After dying, he is reborn with the bloodline of a demon god, a peerless face, and the power to destroy the world. The first person he kills is Zhou Xiaomo. Then he slaughters an entire city in one night, followed by a country, the cultivation world, immortals, and gods, until every living being is dead and he is left alone for eternity. The only person who can stop the male lead seme from going mad is the male lead uke, a self-sacrificing, saintly hero.

Now the plot has reached the moment when the male lead seme is about to be burned alive and reborn, so Zhou Xiaomo hurriedly goes to save him. Too socially anxious to face his cold gaze? Then she'll quietly bring him medicine and meals when no one's around, and discreetly monitor his recovery from behind... In short, she has to keep him alive so he can't be reborn. She also needs to find the male lead uke so they can fall in love and save the world.

Much later, when the male lead seme and male lead uke have their fated encounter, Zhou Xiaomo plans to bow out. But she hears the male lead seme say to the uke, "She actually loves me. She's just shy and acts cold, but she's warm inside."

"Her love gave me a reason to stay in this world."

"I'm going to marry her."

"She seems to praise you a lot. If you don't want to die, stay away from her!"
