Heh... those can be amusing, as they can lead to some awkward situations. I think the thing that gets me about those, is that they tend to overplay the awkward circumstances. For example, Amano absolutely adores the otaku girl's games and plays with her all the time without knowing it; however, they can't agree on otaku-related discussions and "hate" each other. Well, that other guy knows both of those facts about the two, but while he keeps hinting toward it, it gets to a point where I say, "JUST TELL HIM!"
The last episode was fine mostly because of the end where he inadvertently asks Tendo out because he repeated the line from the game. While the rest of the episode was a bit lackluster, that bit makes me curious what they'll do in next week's episode.
