I think everyone wants this guy to disappear but at the same time I can't help but feel it a little bit sorry for the guy. He's not trying to fuck up everyone's day but he is just by existing and being himself. I can certainly see why he thinks Hime is cute, though.
Hopefully he grabs a clue sometime soon, but knowing this series it's going to get really stupid first. I can't call it unrealistic, but it's so awkward.
