After I Faked My Death, the Male Lead Turned Dark

[Two male leads + they fall in love before turning to hate + the scum-chasing redemption arc] Jiang Yanqiu transmigrates into a minor villain who envies the male lead's talent. The System tells him that if he can keep the protagonist from turning evil, he'll be able to return to his original world. Jiang Yanqiu: No problem. Easy! When the male lead is in danger, he risks his life to protect him. When the male lead is cursed, he offers himself to cure him. When the male lead is framed, he takes the blame… Jiang Yanqiu raises the male lead little by little, but why is the male lead's gaze growing stranger by the day? Later, with the System's help, he fakes his death and returns to his original world. But before he's even had a few days to celebrate, the guilt-ridden System tells him the male lead has turned evil and orders him to hurry back and save the world. Only for the male lead to pin him against the wall: “Where do you think you're going this time?” Jiang Yanqiu: “Can someone tell me where my sweet little lamb of a male lead went?!” “Only after loving someone do you learn what it means to hate them to the bone.”
