Beomgyu is an omega lupus. He doesn't like alphas very much, he's always on the defensive, he doesn't like being touched or ordered around. He's handsome, not very short, but not very tall either. He's an idol, plays volleyball, is a model and an actor. He's 19 years old and debuted in a K-pop group at 16, called Tomorrow by Together (TXT), where he's the only omega. Well, Soobin is a beta, who looks like an omega, but Beomgyu knew it wasn't the same thing.

The rest of the members, Yeonjun, Taehyun, and Hueningkai, are alphas. Only Soobin is a beta, and he is an omega, and Beomgyu hated that. They were always getting into trouble, especially him and Taehyun. Taehyun is an alpha lupus.
