I liked it
I don't care that there isn't much of a developed narrative or whatever going on, it looks good, Ayu's beautiful, there's meaning to match the song...
I mean, so many other artists out there have this kind of 'boring' one or two scenes PVs as well, but they don't take away my audio or visual enjoyment if the song and the PV suit each other. At least there doesn't seem to be any awkwardness like in Mirrorcle or GREEN.
And I'd have to disagree with the 'ordinary' comment. It's not spectacular (for now at least), but it's distinctly Ayu. Reminds me of Moments and Marionette too, which are great PVs.
