^ It's surprising how little subtext there is in the anime itself. There's a hint of UzuRin of course, and in the first season there's a bit of Mio x Ranko. Second season has some background Kaede x Mizuki, and Kirari x Anzy if you really squint. I couldn't even see Natsuki x Riina in the show itself, which only showed them as friends with a similar interest.
