Like some of the characters look like they're based off stereotypes, but they act almost in a completely different way or have other tropes applied to them (Shikatani seeming like the serious type; nerd even but is pretty much a tsundere, or even the mom of the group with how much he cares about everyones wellbeing). And then you have the main protagonist, Toono, whos the straight man of the group (hah) and gets roped into this horny mess of a club and it's just amusing to see how he tries to get through it.
Refraining from spoilers but it's kinda misjudged with all the hentai but its got a pretty decent plot. Only downside is how long it takes for the manga to update since it happens randomly but its understandable.
