How to advance relationship with yuna? It's stuck at 40 points and I can't increase it also sometimes during night events the option to click on the sheets does not appear
You can get hint from her what to do if you start night, living room, give gift, chat with her
As for the clicking thingy - bug, restarting the game solves the problem temporarily, iirc it should be fixed in the latest paid build, which will soon become free
Go running at night in the city to buy her a pair
