I was expecting this to be very light stuff, and thus it having a bit of weight came as a surprise to me. A positive surprise, of course. Kirino's absence naturally made it all the better, but looking at it from another angle, Kirino having been annoying in the rest of the show gave this a directly undeserved boost as well. Nevertheless, this was a positive surprise because it wasn't composed of only tsunderely cute Kuroneko with empty dialogue.
Good details were Kyousuke realising he doesn't know Kuroneko's real name, the club president being the bike owner, and the other chick being the little sister of the homo queue guy. Jolly good details indeed.
