ABO setting.
Everyone at the affiliated high school knows there are two school bullies. Everyone thought they'd fight for power when they met, but no one expected them to develop a brotherly bond in the spirit of socialism!
One is Jin Peifeng, an Alpha who stands tall and proud. He's cute, and his pheromones smell like Want Want milk.
The other is Xu Yizhou, an Omega who has wanted to be an Alpha since childhood. His pheromones smell like ginger.
When they were in kindergarten:
Zhou: "I'm definitely going to present as an A. You're so cute, so you'll definitely be an Omega. When we grow up, let's get married, okay? I'll bring you Want Want milk candies every day." Jin Peifeng agreed because of the milk candies.
But by their second year of middle school, Jin Peifeng presented as an Alpha. Thinking back on kindergarten embarrassed him. He figured his pheromones smelled like Want Want milk because he'd eaten too many milk candies, and he came to hate Xu Yizhou even more.
In their second year of high school, they were placed in the same class. The sweetest A and the most arrogant "A" met again, ready to settle their old and new scores. Both were Alphas, and neither thought much of the other. They agreed to meet in the woods after school and settle it in a fight. But before they could throw a punch, the arrogant "A" dropped to his knees, burning with fever, and passed out.
When Xu Yizhou woke up, he found the sweet A staring at him solemnly. "You're an Omega."
From then on, an Omega who had aspired to become the strongest Alpha in history lost his dream...
