Mystery Volleyball ABO

The age of 17 is the peak period for summer sickness. Hundreds of years ago, some humans evolved and acquired secondary sexual characteristics in addition to gender. At the age of 17, when hormones and pheromones are most active, along with anxiety and high fever, boys and girls will undergo a second screening that changes their destiny. ——Secondary sexual characteristics: Alpha and Omega. Alpha is the embodiment of ability and strength. Social resources will be tilted towards Alpha, and they can be found among the best in all walks of life. Omega is weak and needs protection. The body with fragile glands and reproductive cavity actively becomes soft in order to conceive, and the mental and physical tolerance will be greatly improved. In addition to the innate conditions of the differentiated person becoming more superior, Alpha will be susceptible to pheromones and extremely unstable emotions, while Omega will usher in a rainy and dew period in conjunction with Alpha's pheromones. Alpha can only be comforted by Omega, and only Alpha can mark Omega. These two complementary sexual characteristics attract each other and at the same time control each other firmly. This massive division was like a sudden thunderstorm on a suffocating summer day. But no one knows how long the rain clouds will accumulate before the heavy rain that extinguishes the warmth in the heart will pour. Only the anxiety during the differentiation period will continue, so some people will always call the differentiation period at the age of 17 the coming of summer sickness. Those who have not differentiated during the entire Summer Sickness period will eventually be collectively referred to as Betas. This is an era where the majority of mortals (Beta) and the few chosen people (Alpha Omega) coexist. Ever since Yanagi Sakuya met Kageyama Tobio, she knew that the other person would definitely become an Alpha in the future. But even so, he still hopes that the other party's pace can be slower and slower. ＊The story is based on the world view of volleyball and added with ABO settings.
