In this world, people are categorized into one of three secondary genders: alphas, betas, and omegas. Alphas (α) are seen as society's elites. They find success in any endeavor without the need for much effort. Betas (β) are seen as the "average" and most populous, without major alpha or omega traits. Omegas (Ω) are perceived as unfortunate souls, bound to their heats that produce strong pheromones, sometimes strong enough to attract even betas. Hayato Kujo works hard, uncharacteristic for an alpha. But no matter his feat, everybody around him attributes his success to his alpha genes, except for Kaname Yao, a classmate and teammate on his high school's track and field team. Yao views Kujo as a rival and serious athlete, regardless of their genders: Kujo an alpha and Yao the beta...? Wait a minute... Yao was surely not prepared to get all mixed up in this alpha-beta-omega-fated-mate-bond stuff.
Howe and Torao had firmly believed they were fated mates destined to be together. Till the day their "Secondary Gender" test results came revealing that they were both Alphas. Leading to Torao breaking off their relationship.
Genjirou Momoyama is a poor and unpopular omega, and suppressants don't work on him. Every time his heat comes, he has to go to an omega shelter, and it's tough. Touji Sakurada, a high-end alpha who owns a leading pharmaceutical company in the development of suppressants, falls in love at first sight with Genjirou as his "clinical trial subject." Genjirou, tempted by the reward, agrees to be Sakurada's subject, but starts getting tired of Sakurada's research and constant monitoring...! An omegaverse romance comedy starring a rich alpha who wants to save omegas and a poor, big, unpopular, and non-standard omega is here!!

On the other hand, there's the new kid, number two host Leo, who doesn't have to pretend to be effortlessly cool - he just is. Now, what happens if one of their dear customers demands these two alphas take each other to bed?
