I was wondering if there were any really good h-mangas set on an onsen trip. Preferably harem or group, though one-on-one with a couple or soon-to-be couple is fine. It can be a piece of a larger manga, or a oneshot, or anything. Only thing is that if it's harem, there aren't any other guys with major parts in the story, and if it's group, there's no one left out and the main character, if there is one, is the most popular/desired guy there.

A while ago, I saw a piece from Chunrouzan's Friend set on a hot spring trip, a piece that I really hate. I'm hoping to see something that goes in a different direction, something like what the main character of Chunrouzan's work was planning, either he gets the girl(s) to himself, or he becomes the one guy at a group "party" that every girl wants a piece of.
