Reforming the Worldview of a Chauvinist Alpha (Omegaverse, Switch Couple, Omega Top)

(The story mainly features an O who tops and an A who bottoms. The main plot is about the O taming the A, but the A used to top, and the early chapters include the A mistreating the O, so it's listed under switch couples.) ++++++Even after fifteen years of marriage and having a son and a daughter together, Chu Lin, an omega, understood perfectly well that in the eyes of Qin Yu, an imperial general and an S-rank alpha, he was nothing but an accessory, a toy for satisfying his lust. Chu Lin was not willing to accept that. Over the course of three years, he secretly altered his and Qin Yu's glands. One day, on his way home after a meeting, Qin Yu suddenly found himself going into heat for no apparent reason, despite being an alpha. He staggered home. His omega sat on the sofa, watching him with unhurried amusement. His thin lips curled slightly, and beneath his glasses, his eyes were calm. Qin Yu's eyes were bloodshot, but he couldn't move. Chu Lin slowly pushed him down and pinned him beneath himself. "My dear general, from today on, you belong to me. And I will be your master." And so Qin Yu discovered that he had become an alpha who couldn't leave his omega. And the only omega he could rely on was his longtime lover, Chu Lin. This is a story about reshaping the worldview of a chauvinistic alpha. - Male chauvinism means believing men are superior. The term should technically be "A chauvinism" here, but that sounds awkward, so I just left out the first part. - A queenly O x an A who starts out a straight-laced guy and becomes a devoted puppy later - 1. The A has always liked the O, but he used to think it was only natural for the O to do things for him, seeing him as an accessory rather than a lover. 2. The O uses his pheromones to suppress the A and make him do things for him. 3. The A used to top the O. After the O altered the A's glands, the O takes the top. 4. This story takes place after Omega, But I'm the Top, Got It? Theme: Everyone should be equal in love.
