Pretty much the easiest way to sum the manga up is 'dialogue about school, dialogue about human body related things, and action doing those things'.
If you want an ecchi/borderline Hentai manga that's short then well this will do it. The art is very nice, it is more cute then more involved which can be odd but seen others do a good job despite this design, and the impact of the scenes are very clear within the first 2 chapters and it's only 7 chapters long (two .5 chapters). It has an 'action' scene every chapter and breaks in-between moments.
It does a fair job of the dialogue, whether completely accurate of I assume an educational angle I don't know, it isn't Futari Ecchi in-depth and references alongside that but it is fairly relatable to that manga in the situations/purpose of each chapter and of course being just engaging ecchi moments depending on the moves/interactions people may feel in the scenes (besides the newlywed couple of Futari Ecchi instead with highschoolers and of course with no graphs/references and more just spoken dialogue about the subject matters/actions the characters are going to do and then do it). Though in this manga I do think some parts do seem off. Like in a way a 'I'm saying this and this dialogue about this thing' while action is going on can be a bit ridiculous but other times it's more normal and flows better.
In short it's about two-three highschoolers, one is a female model (Onda, Eletrika and we do see her job around the chapters of her introduction) that only serves to intervene and be a rival character and appear from time to time, the lead male (Yabusaka, Makoto) that approaches the female lead (Mimibukuro, Chie) in Chapter 1 and from there they just connect by talking about what both fascinates them and ecchi moments happen from there chapter to chapter.
The ending is pretty simple, a girl is picked, they work out their futures past high school and they live happily. Simple as that.
Very simple story, it's clear your reading/looking at the art for the ecchi moments with this one as clear as that. It makes up most of the manga and it's the goal of the manga to just enjoy it.
