...idk if he would be dateable at all, ever O_O Without giving spoilers I just don't see that as a possibility for him
I see it being possible. Perhaps MC could make him a better man, even if it won't be that simple. Kyrex says he can't be in a mongamie relationship, but I'm sure he's wrong. He just has't found the right guy.
Or... he could... be in a relationship that's not monogamous, like a normal person?
