The Villain Doesn’t Want to Live [Quick Transmigration]

As a villain, Huai Shi has always done whatever he pleases, including, but not limited to, humiliating, bullying, and crushing the young protagonist. Now he has returned to the timeline he drove to the brink of collapse, facing the boy who is as insignificant as an ant. The System asks him to change the protagonist's fate and prevent the world from falling apart. Sorry. If he had another chance, he'd still make the protagonist kneel all night in the snow. After all, he doesn't want to live anymore either. :) *Has the protagonist gotten revenge today? *LOL, no one's getting revenge at all. *The protagonist is crying and begging you on his knees to forgive him. "Ancient setting" "A cold, peerless formation master" He lets the other man take revenge, sets him free, and puts the world in his hands. So why is he crying and talking about staying together forever? . "Ancient setting" "A puppet emperor who hasn't long to live" "Brother, are you going to make me die in the crown prince's place, too?" "I forgot. You're the crown prince's brother, not mine." . "Interstellar" "A mentally unstable marshal" Hello, aberrant. I am your creator, your savior, your guardian, and your keeper. I don't want this job anymore. When are you going to kill me? :) . "Post-apocalyptic" "A secret operative on the verge of self-destruction" I'm here to frame you. I hear I've become corrupted, fallen, and rotten. Please don't save me. . "Xianxia" "A demon seed by birth" "Your merciless path is going to shatter. What does that have to do with me?" Tips: 1. One-on-one romance, melodramatic and unrestrained, with sugar and glass shards. 2. The protagonist has a slight self-destructive streak and appears already injured. 3. A peerlessly beautiful man who gives up on himself, and a love interest who would rather die than let go. I can't even sum up the love interest's type. 4. In short, the love interest is utterly devoted. 5. Happy ending. 6. I don't know what else yet. I'll add more if I think of anything. It's probably a melodramatic tale of love and hate, and I hope to create the kind of story I'd love to read myself... Theme: After traveling through mountains and rivers, we always meet again.
