So, in Japan, Onsen are not big enough to swim in generally. Finding an onsen that is around a meter deep is rare. They are usually deep enough to reach your chest depending on how you sit or kneel.

Thanks to these photos, we know how deep the water really is.



Meaning in the original photo…

…they are sitting or kneeling beside one another. If you look closely at Yurio, you can see his knees, so he’s sitting.

So as the water isn’t deep, and Yuuri is so close to Victor, you can bet they are sitting beside each other, naked(as clothing is not permitted in onsen) and touching lightly at the very least. So as Victor’s arm is wrapped so firmly around Yuuri’s shoulders and he’s too close to be leaning into the hold… infer what you wish.
