It is definitely being set up that if he does get in some kind of romantic relationship it will be with the neighbor. She matches with him in a lot of ways, more so than most others ever would, and she sees the good qualities while also seeing that his personality SUCKS. Guy could change, but it is doubtful. He is on his second life of acting the same way, ain't no way he is changing his mind on much.
I guess it doesn't really matter in the end if he ends up in a relationship, but damn does his personality need to calm down a tiny bit lol.
