I was pleasantly surprised by this as well.
It's nice to see a romantic anime set outside school for once. I too was expecting some weird story to develop, but it feels like it will keep its pace. The older characters are a nice change as well. I'm really curious where they'll go with the story considering the circumstances (I'm avoiding the manga as not to spoil anything).
The animation, backgrounds and colours were particularly well done. Can't wait for the next episode.
