well it's pretty childish to try and harm the one that was just too afraid to become the direct target themselves bc it all depends on how you yourself would react if you were that person instead, but it is also not expected of you to fall for them, so it rlly depends on the person. I'm the time to hit back harder than whatever someone else did to me, but this guy was one of the ones that just stood there so I would have confronted him about the situation first if anything (ehem then I guess I would find out why they wouldn't do shit).
and he did despise him until he learned he was an omega and then he realized he was doing to Gyojin what was being done to him.
He had been enacting revenge because he thought he had been wronged unfairly (which he was), but when he learned Gyojin was the rumored omega, he could understand why he never spoke up. That is also why he apologized. Ryu had already wreaked revenge on Gyojin, but its something he still should have never done (abuse of power) since Gyojin did it out of a very real and potent fear.
To be honest if that had happened to me I would've been OUT FOR BLOOD. Like, it pisses me off everytime I end up taking the fall for something that has nothing to do with me, but this? Aw, heckie naw! I would've worked that Omega to death, and I sure as hell wouldn't have fallen for him..... But I probably would've forgiven him eventually after letting my anger out REGARDLESS THOUGH, GREAT STORY!!!! I JUST SAYING, I WOULD HANDLE D THINGS WAYYYYYYYYYTT DIFFERENTLY (even though I know it's not the omegas fault). Like, if you met someone who bullied you from the past, and all of a sudden you're higher up than them, you'd wanna teach them a small lesson, right? Even if you knew they were not the one's physically or mentally hurting you?
