Looking for a manga with omegaverse genre.

You could say that one theme in the manga are bee (hachi) and bear (kuma). The omega is the "kuma" and the alpha is the "hachi". You can see it very well in how the omega likes to dress himself when at home.

They are both delinquents, but the alpha is from a yakuza family, while the omega is just a normal delinquent.

"Hachi" didn't know at first that "Kuma" was an omega, until he got his heat. (Not sure if "Kuma" himself knew or not).

Is this it?
