>Is that the anime where she only pretends to go outside?
Kinda. The series (manga, anime etc.) is about a bunch of schoolgirls forming a hiking club, generally being wannabe socialites, and trying to pressure the one girl who just doesn't give a fuck and actually goes out all the time (well, what japs consider going out, anyways - driving to a curated campsite, setting up way too much gear, spending time in what's effectively a park, then driving home the next morning) to join them. That "hiking club" does pretend to go out a few times, and "camps" in the classroom with cardboard boxes instead of sleeping mats, trashbags instead of sleeping bags and tarps, electric cooking gear etc. iirc, once they can afford basic gear, they start going "outside" (again, by jap standards), too.
