Well, I'm glad that this show avoided a simple love triangle (or worse a love rectangle). When Sentaro screwed up the invite, I feared a rectangle was forming. Fortunately, it appears that Rurika only has eyes for Sentaro. And Sentaro is such a big, lovable dork. I thought he had major guts at first to ask Rurika out
in front of her friends, but he just doesn't know any better.
The scenes with Sentaro's family were great too, a huge contrast with Kaoru.
I finally noticed this episode that everyone's jaws move when they talk. That's rare to see in anime, mouth flaps with no moving jaw are one of the things that makes anime look so cheap sometimes.
