Haikyuu x seme male oc (rewritten)

Hayate Saito is a high school student who just graduated from high school in America and is going on to university in Japan for a change of atmosphere, but being a horrible person when it comes to time management he wasn't able to complete the community service hours that were required at his high school, so even though he came to Japan, he was still required to finish his hours. Due to his love and passion for volleyball, he decided to volunteer as an assistant coach.
