Transmigrated as a Villainous Cannon Fodder, I Was Forced to Become a Madman's White Moonlight

[Unhinged, Brooding Male Lead] [Both Leads Are Chaste] [Redemption] [School Setting] [Happy Ending]

Yu Yang transmigrates into a book, becoming a disposable supporting character. In the original story, she hurls abuse at the male lead, Xie Zhou, and beats him constantly. After the original Yu Yang torments him so relentlessly, Xie Zhou turns dark before the heroine even appears and kills her with a single slash.

System: [Mission: Stop Xie Zhou from turning dark ahead of schedule. Remember, the male lead Xie Zhou is brooding and unhinged, obsessive and extreme, calculating, twisted, and devious. Be extremely careful.]

To finish her mission and get home as soon as possible, Yu Yang treads carefully every day, afraid she'll bite the dust at any moment. But how is Xie Zhou brooding and unhinged? He's clearly a sweet, obedient puppy who follows her around calling her big sister.

Yu Yang refuses to believe it.
