After Landing in an ABO World, I Changed from an Alpha to an Omega

Screenshot taken on 7.13. Both protagonists transmigrate. Lu Ze is the notorious school bully at Tianye No. 1 High School, but he's also ranked second in the entire school. The head of discipline hates him to the point of grinding his teeth, but can't do anything about it. The school bully secretly considers the top student his archenemy: Su Zichen, who beats him in every exam. Unfortunately, before Lu Ze could ever beat him in an exam, he got into a car accident. When he woke up, he had transmigrated into an ABO world, into the body of someone with the same name and appearance as him. In this world, he wasn't just an academic failure, but also a weak A who got bullied by betas. Right. An academic failure. A weak A. Lu Ze smiled faintly. Later, his classmates were horrified to discover that the weak A in their class had suddenly gotten stronger. His grades had shot up to second place in the whole school, too?? Lu, the Perpetual Runner-Up, Ze: "..." Why was there a Su Zichen in this world, too? Not only was he the top student, he was also the dream omega of countless alphas at school. If he couldn't beat him academically, he might as well give up. Taking advantage of the difference between alphas and omegas, Lu Ze lazily decided that there was nothing wrong with picking on him a little. In the end, Lu Ze failed to bully him and was pinned against a wall and marked by the top student instead. Only then did he realize: when had he changed from an A into an O, and Su Zichen from an O into an A??! Held in his archenemy's arms, the boy buried his face against Lu Ze's neck and said in a cool voice, "Your pheromones smell so sweet." Lu Ze: "..." Weren't I supposed to be an A? Theme: I will definitely find you.
