So does it mean that being bitten = being marked? I don't really get the issue with the collar too...really appreciate if you can explain it to me...
I don't think just because the omega got raped, he will get pregnant for sure right?
(Spoiler: Since the omega has a partner who bite him in the past, does it mean that the omega had been marked and taken? Then, Ougi has no chance of being together with the omega? This is so sad!

omega here was not in heat, that was helpful. And Alpha did not ejaculate apparently.
( This story is dramatic, the omega was marked by Ougi when they were childhood friends , they did not know of the Alphas and Omegas , someone else pregnant to omega ( but he had already chosen Ougi ) he was one of the people who cared for him and he had to abort . then he left the city .)

it was hayato who raped him, but since hayato didn't bite him kanae wasn't mated with hayato. yuu-chan was hayato's partner, and he was driven solely by his instincts he couldn't resist when he raped kanae so that's why he was chanting apologies... and kanae was already marked by his mate (with whom he had not do the deed yet)
Getting penetrated is not equal to being mark by the guy who penetrated u? The omega was clearly raped n penetrated by that yu-chan, but the omega said they didnt do it and he hasn't been marked? Is it when an alpha cums inside the omega then it is counted as him being marked? Nonetheless, it doesnt change the fact that the omega was raped by this yu-chan. If only ougi had saved the omega in time!
