In the novel it was said that mc was pinned down and said he couldn't fight back because he's an omega in heat and the alpha pheromones was making him unable to think straight. It wasn't described specifically but it is written on the conclusion that MC was raped since he did bit his hand until it bled and stab his palm with his nails for him to comeback to his senses and throw the lamp to the attacker and stab him with the shards.
So who's that person who gave spoiler saying mc was graped. That didn't happen. It was an attempt and luckily mc deflected it. For past 20 ch I was all like mc was graped.
