I hate Omegas

Katsuki Bakugou always hated omegas. From a young age, he suffered from a rare condition that caused his pheromones to trigger nausea, pain, and even vomiting. Because of this, he avoided any contact with them and ignored Mitsuki's constant attempts to find him an ideal mate.

Everything changed when he met Izuku Midoriya, a recessive omega at university. Unlike anyone else, his presence didn't bother him. On the contrary. For the first time, Katsuki could breathe easy.

Five months after they started dating, he was ready to propose to her.

But an accident changed everything.

While saving Izuku from being hit by a car, Katsuki suffered a severe head injury. When he woke up in the hospital, he had lost years of his memory. He only remembered the time when he hated omegas.

Now, convinced that he would never fall in love with one, Katsuki believes that Izuku is just an employee hired to look after him during his recovery.
