hiro

(Hiro is an omega lupus who studied at a school where he didn't fit in. He had an ethereal appearance, and many people made fun of him for no reason, so he spent most of his time alone, wishing he could change schools. One day, his mother said they were moving to another city. They moved, and his mother enrolled Hiro in another school. Everything was fine when Hiro went to class with the other freshmen. As they went up the stairs, they ran into all the school's upperclassmen, who were coming down the stairs going somewhere. On the first day, Hiro already saw the upperclassmen: many alphas, some omegas, and other betas.)
