I like the PV for "Hatenai Sora" better than the PV for "Dear Snow", that's for sure! I really love the setting with the buildings and the water.
I just wish there would be more going on than only walking/standing and singing.
But lets wait and see, it's only a short preview. Maybe there will be more...*hopes*
I have the feeling that there will be something more...the passage where the light is shining through looks interesting to me; maybe there is a surprise waiting for us!
