Its part of idea/scene in of my Rps with my friend Shenade.

They are on some other planet as Ellie learns to control and master her goddness power within her as her guide is Alona(ruler of the planet)
and for whatever reason we decided it would be cute funny to add an random hot spring scene into the mix
this is her characters planet, we just decided that everyone on said planet was pretty like... "open" do they have mix female and male hot spring/ baths.
Dante and Ellie still getting used to being around each other naked, make it a bit TOO intimate for them so they keeping a good amount of distance between each other
while other two, Leighton and Sereno just seem to find the amusing considering that's how they were sorta at the beginning of their own relationship
