I was only able to watch it just now in really low quality...
But I made a GIF of the scenes. (it's about 5MB)
Ayu sings on the rooftops in a white flowy dress and is also a painter in the park who cries later in the PV(?). The video looks stunning. And there are a lot of sped up scenes of the city which reminded me a bit of Namie's Alive.
The GIF (very large file, so please be forewarned)

The PV now gives me progress vibes now that I watch the preview again.
