Katsuki Bakugo is a very respected Alpha and one of the strongest at U.A . No one dares challenge him if they value their life. To everyone else Bakugo seems like a cold and aggressive person, however he has a soft spot for one little omega. Izuku Midorya is small and beautiful, a valuable mate. Regardless of Katsuki's constant bullying he still had a massive crush on the aggressive male. One day Izuku goes into heat without any suppressants. This catches the attention of every alpha at U.A including the crimson eyed male.
