Hmm the story I read sounds more like this....Alpha #1 forces another alpha to submit thru rape not pheromones in order to take revenge on said alpha raping an omega....
Then we get a backstory..said omega was actually Alpha#1s childhood crush/friend who left town after being raped & impregnated by his own brother and had an abortion. Years later the rapist brother decided to live as a submissive alpha to make up for what he'd done to his omega bro and the loss of his unborn child.. anyway he does some investigative work to help reunite his bro with his first love. Fast forward to the present, the omega, Kanae gets into an alpha HS where his boy alpha #1, ouigi attends. All the alphas try to get him to choose them and one of the claasmates, hayato rapes him. Ougi rapes that alpha, hayato, not sure whether it was out of revenge or sexual frustration since he also felt an urge to rape Kanae, or both. Ouigi also befriends Kanae in an attempt to win him over, never realizing this was the same person he loved as a kid. Meanwhile ouigi gets the school to let hayato back in if he takes suppressants...those drugs make hayato so helpless the class decides it's better to forcibly rape and mark Kanae than watch rapist hayato take rut suppressannts ( it was the biggest WTF moment for me, the reader)..yada yadda yada...fortunately bad weather and mudslides foil their plans. Eventually Ouigi and Kanae confess and become a couple. The end. It melted my brain and made my heart vomit. U HAVE BEEN WARNED. This story sucks.
