Probably.
But when Nika's hand is under Ayua's skirt, it's because she put it there herself, drunk or not. Ayua is not a girl who'd let herself to be groped without permission and Nika is still not a guy who'd put his hand under a girls skirt himself even if he had the permission
However, what I noticed besides the girls is what it looks like a notebook PC on the table where Nadia is sitting and a projector with another notebook on the left. And what it looks like Nancy, Sasha and Nika are looking at the camera, they might be looking at the projector screen instead. Makes me think where exactly are they and what kind of an event is this. Looks more like a class or a conference room, or maybe it's the library? And how come Ayua is drunk there?
