All the Protagonists I Hurt Were Reborn [Quick Transmigration]

Just as people don't remember what they ate for an ordinary meal a week ago, Xi Xingyue never dwells on every part of his long career as a cannon-fodder character. In short, after completing every achievement for a glorious cannon-fodder career, Xi Xingyue accepted his trophy and prize money and began his speech. He had only memorized one fifth of his five-thousand-word speech when the main System tossed him back into every world he'd experienced before. ① Underling enforcer who keeps his head down, top x reborn straight guy who rises from the ashes, bottom (A touch of cyberpunk and supernatural elements, disasters and pollution) Xi Xingyue lived with the protagonist as his older brother, relying on each other for support, and fell in love with him after he came of age. This shameless cannon-fodder character used every trick in the book to force the protagonist into a relationship with him, twisting himself into a possessive, obsessive mess as he begged and coerced the protagonist to love him. This time, the savior who was supposed to coldly reject him and stab him in disgust agreed without a second thought. Xi Xingyue: Huh? Bro, can you at least stick to the script? ② Taciturn regional leader, top x reborn mad-dog spy, bottom (A touch of steampunk and high-martial-arts elements, extreme cold and the apocalypse) Xi Xingyue took the protagonist in when he was down and lost, drawing close to him, warming him, and prying open his defenses. In return for his kindness, the protagonist bit him back. Xi Xingyue didn't care in the slightest, still bringing his lovesick heart to the protagonist. This time, the protagonist, who was supposed to avoid him and go through the whole cold-shoulder-and-betrayal routine, clung tightly to Xi Xingyue and apologized into his ear. Xi Xingyue: Huh? Who possessed the protagonist? ③ Arrogant, scheming Omega, top x reborn domineering CEO Alpha, bottom (A touch of futuristic space opera and ABO; the CEO comes with two adult collateral-branch adopted sons) Xi Xingyue was deeply in love with the protagonist and dead set on taking him by force. He used his Omega status to manipulate public opinion, pressuring the protagonist with both their elders and the public, and got his wish: the two followed through on the playful marriage pact their elders had made when they were children. This time, the protagonist, who was supposed to avoid Xi Xingyue on their wedding night, pushed open the bedroom door, determined to fulfill his duties as a husband. Xi Xingyue: Huh? I'm begging you, bro. Go out the door and turn right, grab a vase, and knock yourself on the head to see if there's something wrong with your brain. Xi Xingyue in the first life: Everything under control. He clocks out right on time, unruffled. Xi Xingyue in the second life: Bro, is this even still a cannon-fodder script? Where the hell did I wake up? *Addendum* Top-focused, and more or less both of them are reborn. The overall dynamic: A cannon-fodder top with nerves of steel and achievements that matter more than anything x a bottom who comes to his senses after being reborn.
