Bokutachi wa Unmei ni Kirawareteiru (Yaoi)

The following content is intended for mature audiences and may contain sexual themes, gore, violence and/or strong language. Discretion is advised.

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. (Warning: Mentions of sexual
assault)
