There's not much point in it, frankly. I'd liked Season 1 overall, despite strongly disliking occasional episodes. I liked the story it was telling of Ui Wakana, Hayato Izumi and their evolving relationship. Wakana and Izumi discovered that they'd been promised to each other by their parents in an arranged marriage, so Wakana's moved in with Izumi (in the teeth of his objections) and calls herself his wife. You get this a lot in anime. No, really. What you don't get so much is a clear-eyed look at how this relationship might develop sexually, with a grumpy Izumi in denial half the time but still liable to respond to explicit situations.
I was charmed by Izumi and Wakana. What I'd disliked was this relationship being undercut by Izumi's sexual activity with the other girls who'd started to show an interest in him. (He's just as grumpy towards them and no one actually has intercourse, but it's still adults-only material.)
Season 1 was strongly focused on Izumi-Wakana, though. The other girls only got in the way occasionally. Season 2, though, has more of a harem formula, with Rin Misumi getting as much screen time as Wakana while other girls like Niikura, Fujisaki, Honoka Saijou and Rin's older sister all get their share of the spotlight too. (No mention of Wakana's mother, though. That would give too much focus by association to Wakana.) This reaches its nadir in ep.9, when Rin is the one who gets sexy with Izumi for an unofficial photoshoot... because they drew lots for it and Wakana lost. Why should Wakana be having to draw lots? What's supposed to be equal between her and Rin, beyond writer-imposed harem balance?
I don't want this show to be ecchi harem nonsense. Season 1 had a purpose and was saying things about its couple. Season 2 isn't saying anything except "look, he's sucking her nipples!"
It's implausible even by the low standards of harem anime. Had Izumi been yet another generic nice hero, this show would have been identical to a million other bottom-feeding wastes of gigabytes, but at least I'd have been able to believe in his actions. Izumi keeps refusing to have sex, even when naked girls are making him fondle their boobs (and more). If he'd been a nice guy, I'd have bought that. I'd have been rolling my eyes, but I can imagine such a character being obsessively respectful, not wanting to take advantage of his friends and so on. This Izumi, though, is a dick. He doesn't seem to care much about anyone's feelings, given how offensive and unpleasant he can be when defending himself against true accusations. He clearly has a fully functioning libido, so I have trouble believing that such a character wouldn't just accept the opportunities.
Similarly it's unclear why all the girls should be targeting him. Do they all like bad boys? Maybe, but Izumi's capable of being abusive. Also we still have the annoying plot device of Izumi and Wakana having been keeping their relationship secret for the sake of genre formula.
Ep.3 is particularly eye-rolling. The school photography club is selling indecent photos of female students... but the club's members are girls too! Yeah, I'm sure that happens all the time. It all ends up getting laughed off, because girls. The answer to everything is girls, or possibly big boobs. (Small-breasted women do not exist in this show's universe.)
The writing forces itself into contortions to set up its sexual situations. In ep.5, Wakana catches a cold and gets given medicine. It's a suppository. Of course. Did they think she was in a coma or something? Anyway, Wakana thinks putting a pill in her bottom would be scary, so she asks Izumi to do it.
I don't much like this season, but I'd probably watch a third one. (The show would then undoubtedly continue its downhill trajectory.) This season disappointed me, but there's still just about enough here to keep me watching. I didn't hate it. There's enough exploration of Wakana's character for me to care, not to mention occasionally also for side characters like Fujisaki in ep.11. There are Wakana-centric episodes. Ep.8 is nice. She's sharing more of the spotlight now, but that doesn't mean she's completely sidelined. The show hasn't entirely lost its mojo yet... but then they'll do a three-way breast fondling comparison scene in public and you'll realise that that kind of "mojo" is something the show's actively trying to discard.
