My Pheromones Are Bonded to the Campus Heartthrob's

When Sheng Yangchu was fourteen, someone transmigrated into his body. After discovering that his world was a book, he spent three years watching the transmigrator, who knew the plot inside out, turn a winning hand into a complete mess. They turned him from a top student in the top ten of his grade into a failing student at the bottom of the rankings, and made him a school bully, an O who bullied omegas and used his status to oppress betas. Then, when his once-perfect, handsome childhood friend, an A, transferred back from overseas, they launched into a crazed routine of melodramatic antics, jealousy, and shamelessly throwing themselves at him. Then one day, Sheng Yangchu discovered that the idiot occupying his body had vanished without a trace. -- Yan Xingchen's life was the very model of a protagonist's, complete with every cheat imaginable. His family was loaded, even the toilet was encrusted with diamonds, and on his first day back after three years abroad, he took the title of school heartthrob. After that, he claimed the top student's number-one spot, too. Every A at school wanted to be sworn brothers with him, and every O wanted to have his children. The biggest regret of his school life was that his once-sweet and adorable childhood friend had turned into an utterly bizarre, clingy O who loved making a scene, forcing him into cold, aloof heartthrob mode. Then one day, Yan Xingchen realized that his childhood friend from back then seemed to have returned. -- Sheng Yangchu: Time to make a comeback. Yan Xingchen: Time to eat my words. -- 1. ABO story. No childbirth in the main story [probably]. 2. Milky A + tea-scented O = Milk Tea CP. This pairing is locked in. Next ABO story: "After My Pheromones Turned A, I Became an O."

Xia Zhihong, the heartthrob of the Imperial Military Academy, the mecha department's top star for two years running, a famous game streamer on the Star Network, and the strongest and most handsome alpha in the hearts of countless omegas... As an alpha among alphas, he had a little secret he was too embarrassed to admit: his pheromones smelled like an O's. So he never dared let his pheromones slip in public, much less confess to the dream O he'd had a crush on for a year. Then He Chuanhan enrolled, not only stealing his heartthrob title but also breaking several of his records. Even the little O he had a crush on publicly confessed to He Chuanhan. In a fit of anger, Xia Zhihong bought a pheromone-conversion agent sold on the dark web by a mad genius scientist. His pheromones successfully transformed into the strongest A scent. The side effect, however, was that he became an O. One injection turned him from an A with O-scented pheromones into an O with A-scented pheromones. Theme: Study hard and improve every day
