This could just be a slice of life series with no actual yuri relationships ever happening. Best not to get your hopes up. That way you can enjoy the series for what it is right now than what you want it to be in the future. If the yuri does ever end up going somewhere it'll be a cool bonus.
The biggest problem with sound and reasonable advise that makes perfect sense is that NOBODY listens to it.
WHere my Yuri at, AYAME/MOE FTW, totes gonna happen lolol
