I'm wondering if the brother rlly hates him or not

I guess he rly like him but is bothered by his brother's action since he believes that the outsiders must stay outside but mc trying to prove that this shouldn't be the case and also the fact that mc is gay too might be another reason. So the brother killing mc's lovers or transferring him to another lab or wtv is somehow just a warning, but this is all just an assumption ╮(￣▽￣)╭

Well spoilers alert....the brother is kinda sus...he is possesive af....it's not a normal like how a brother should hav...uk! Get the hint

Oh man I hope it's not incest
