Wow this series is SO amazing! I'm hooked!
I think the pacing is good. I like animes that move along and don't sit around and drag out scenes that could be just as effectively played out on a faster scale. Having the flashback scene from episode one reapear so suddenly is kinda weird, but it goes with the shows fast pace.
Father joke is still funny, however english teacher falling down gag is getting kind of old. This is even noted somewhat internally as all the students just walk away after she falls.
I think Hazumu is going to go for Yasuna, as she is making all the right moves while Tomari is acting like a brat. However Hazumu might be turned off by Yasuna as she is trying to assume the male role in the relationship: "But if you're a girl, this time it's my turn to court you"
Side note just for Osu!'s sub:
Was the karaoke really neccesary for Jan-Pu's song?
Pu pu pu!
Also I like the fact that you assume that your audience doesn't need lines in english subtitled. Keep up the good work!
