What can I say.
The director of the anime said he loves Makoto way before the anime even went into production, and he sure played with his favorites in this episode.
Looking at the credits, he's involved in this episode much more than other episodes too.
Story development wise, there is only minor progression (Touma getting a tiny hint about Kuroi's scheming ways and something about Chihaya's family), but no problem, because this is a OMG CUTE MOEMOE episode, finely crafted by a man who loves Makoto, for people who love Makoto.
A weapon of mass moestruction.
A scalpel in the part of the brain that governs all control over reason.
Makkomakkoriin.
I actually can't see my monitor right now because I'm teary eyed with the sheer cuteness of the episode.
