At first, it seems the alpha lost his memory of the rape, he was dunk and maybe druged, it's why he could speak with the beta like nothing happened then he recovered or had some flashback.
He also remembered a scene in high school when he saved a guy I think it was the beta.
So I bet the beta felt in love with the alpha and asked the omega to help him to trap the alpha and rape him.
I read the raws on mrm https://myreadingmanga.info/azumi-tsuna-daikirai-no-saki-kara-miteru-jp/ but it's confusing.
Kamiya was bitten but I don't know by whom. Then Kamiya and Ogata are walking together.In the end Ayase and Ogata are close.
If anyone know, your answer is needed.
I know the group update very fast and will soon finish the translation but I am curious.
I ship Ayase & Ogata more than Ogata & Kamiya.
