I wonder if there's a significance to all those wind turbines. They're quite commonplace, and maybe there really isn't anything special about them, but there are a few shots of them from time to time, between scenes and so on.
As for the episode itself, I think it's a good start... pretty solid for the most part. Haruka immediately brightens whatever scene she's in—a perfect fit for her voice actress. Kaoru also caught my attention, and I'm looking forward to that playful attitude of hers.
Poor Tachibana though. The guy practically got friendzoned.
That's one nasty situation to be in, but maybe there's still some hope yet.
