Guessing that the lab wants them to get together, they probably have a hypothesis that the MC isn't infertile, he just isn't responding to alphas that don't have similar genetics to him. Add in the debt that he owes, and the lab no doubt is waiting to swoop in and claim any baby that the two would produce. Alpha probably knows this, and is trying to drive the omega away. What I want to know is what the lab has on the alpha to be able to lock him up. What crime?? was committed by him that they can control him to the extent that they do. And who does the alpha owe anything to, he sure does seem money hungry!
Going to be REALLY honest. I don't really like the brother. His brother was essentially kicked out of the house when he was...16? And essentially had to whore himself out in order to survive. Brother then shows up and is all, "Oh, didn't realize you left home two years ago. Why didn't you say anything?" Bitc* Please! Why didn't you look around and check in on your own family? You obviously didn't give a rat's as* about him!
So all the people were allowed to keep living, who fed off of killing other people, either for sacrificing, or for experimentation. What a load of >.> You let those villagers live, who had already confirmed that they had killed (and were bragging about points and body count, and who was going to report it to the next village up) several folks. They lived, so that they can keep ON doing what they were doing. All so that the MC could feel better, and wouldn't hurt his conscious at ridding the world of people who were evil, and hey, lets face it, purposely feeding the monsters.
As for the experimentation, instead of contacting the other bases and giving them a heads up on what was going on, you just walked out, and allowed them to keep on doing human experimentation. After all, if they had managed to find two such guides in the last 15 years, in a small search radius, chances are that they will no doubt be able to find others who are able to 'guide everyone'. The whole thing was a crock of shi* that was just all wrapped up so that the MC and the ML could all feel good and not have to worry about doing any damage or harm to their own insignificant egos.
Yeah. 5/10 story. The premise started out promising, but the whining and the crying and the forced relationship killed the whole story fairly quickly.
