There really is nothing to this plot. Did they introduce that one guy just to show the alpha is ruthless, and just to say he's going to die because of his pheromones? He killed the man for some unknown reason (*something* about money) and that was that. Guy was there for like, 5 panels.
Omega is suicidal. Doesn't ever develop past that point. He's still hating everything. He is completely and utterly powerless in this relationship too. I'm not even sure you could call it a relationship either.
There is just nothing to this plot. It's not terrible, but it's not good either.
Like someone had an idea, jotted it down, and that's what we got. Not the expanded upon idea.
