It seems that whoever was tasked with creating this piece of... art was also skilled in the arts of psychological warfare. I've suffered my great share of traumatizing yaoi (Shounen Maid Kuro-Kun and Boku no Pico are things I might be able to erase from my internet history but not from my memory, unfortunately) but I never expected to be this shocked by an ordinary-looking yaoi anime. As for the setting - I just gave up on trying to make sense of it once they said that the teachers are common clients in there.
The story begins innocently enough, if you only look at the first three or so minutes of the anime. But it gets real very quick. With the main character joining the Bitch club for some reason (even though he doesn't really want to?). There were a lot of inconsistencies, like the main character seems more surprised that gays exist rather than about what takes place in the club. After that we get a lackluster story about Yuri, ignoring the main character completely. The great reveal at the end feels underwhelming and you're left wondering if this really is a finished OVA.
I won't be unfair though, I gotta give it up to the art team for the work they did. Visually the anime looked very good, the flashy scene cuts were interesting enough. The only thing that really ruined it was the atrocious censorship. Because they wanted to show so much, paradoxically they ended up showing pretty much nothing. I would have prefered the traditional approach of "angles that fix the problem". This "Level C" style censorship was really not enjoyable to watch.
The music - well I'm pretty sure they played like one or two tracks during the entire thing. Nothing memorable but it wasn't bad. What bothered me though was the voice actor for Yuri. I get that he's supposed to be ~super weird~ but every time he spoke he just grated on my nerves so much. Also a weird thing was that rather than the usual awkward moaning that you have to hide in your headphones, the characters giggled during sex a lot? Well I don't know what else to call it. It was kind of strange.
The characters... I guess they loosely fleshed out like three of them and the rest just... existed. Nothing memorable, although the character design was... original in some cases.
I enjoyed this series about as much as I enjoy physics lectures - I don't understand, I don't want to understand and I really want to go home. As for fulfilling its purpose as a yaoi, marketed towards fujoshis - I guess there's something there for you? Mostly you'll find it funny, I don't think there's anything sexy happening during the whole time but hey - maybe you'll think differently.
Overall I think it's ideal for when you need to turn off your brain and relax - or just think about something else for a bit. It certainly crashed mine.
