So, I've been playing this game for quite a while and was surprised to see the options of Brush and Shower in the Bathroom, but to this day they still don't do much, I thought that while in the shower Anna could've entered and be surprised/embarrased when starting the game and join in a later phase. Also the swimming part in the Public Pool, maybe there'd be a way for Nadia or other characters to stare? Sitting down at the Sauna is also a small interaction where it could have either Emma or Kat to just enter and join.
I understand they're mostly just small interactions to make the game feel a bit more alive and is not a priority, especially with the end of the game so close, but I think it could've been a bit more, even if it's just one photo and two sentences to just acknowledge the action.
