The whole ass and anaconda thing was hilarious. But the story isnt that well-developed. Its like far from complete. there are things that havent been clearly told, like how the uke's friend said thigh "sex" is normal, whats up and why the uke being popular, and also the story made it feel like theyve got none other than themselves (which is more or less a good thing if there are some (dark) story behind it, but this manga didnt portrayed it, and theyre just normal student without trauma or hate anything in paticular, so... Thats what it lacks)
