This anime follows all the tropes, however it does it in a humane way that makes it less cringe worthy than some other series of the same ilk.
Strange as it feels to write these words, here goes: This anime has some respect for it's female characters!
The story of them all being in a school club dedicated to romance and the fact that all the girls have fond memories and are enjoying them-self makes this series(2 episodes but whatever) feel a lot more emotionally attached than other that fail to build any romance or lust between the sex scenes.
With the short run time we don't have time for a lot of subplot and our main character moves quickly between one girl to the next (that's not a spoiler, right?). However it does feel like if there had been budget to make this into a full season instead of 2 episodes than it would have been a worthy romance hentai. ( Episode 2 ends on a "To be continued?", hope is the last thing to die.)
