An alpha has a trauma. When he was young he raped a male omega once. He remembered only the act but not the person or how he exactly got to him - just the fact he raped him. He went looking for him the next day but the omega wasn't there. So now he lives with the guilt. He's an university student now. His senpai invites him for a dinner. Turns out he send him to a male omega brothel. the main alpha meets a male omega there. This omega has some muscles - not skinny as ususal omegas. They end up having sex. + It seems that they're the faited pair. But the omega might be the guy whom the alpha raped long ago - it seems like it now and it was confirmed in the end of ch. 3.
