Being born as an omega, Todoroki Shouto was sure his life was over the minute his father told him he would be married off to the strongest quirk alpha, but with the help of his sister he manages to make a deal with the man. If he can become the number one hero despite being an omega, he can be free from the arrange marriage and his father. Determined to prove that he could be a hero despite being an omega, he pushes aside the need to find a mate and even goes as far as suppressing his nature. That is until he meets the quirkless Alpha Midoriya Izuku, who just so happens to be the stepson of the Number One Hero All Might. ( or the one where Todoroki is an independent omega, but becomes adorable only for Izuku.)
