I remember when I watched Episode 2, I was expecting this to be a series of standalone stories without much integration or continuity. That expectation gradually died away as I was happily proven wrong, but boy, this episode mashed everything together so well. I was sort of thinking Kusuda and Kei would have moved on a bit more. 2 months is plenty of time. They just need to go on group dates where their friends ditch them to get out more often, since neither takes the initiative much.
Seeing Kei all flustered is nothing new, but still cute
