OMG, Angel's PV is when a nice idea goes completely wrong, just terrible imo! The beginning looked nice, but then the dancers came and, sorry, I think the dancers randomly dancing around her didn't look nice, they looked comic. And the end is just terribly executed imo. Honestly for me this is the worst pv of this album.
But I enjoyed XOXO, the selfie parody was funny

And I like to see her trying to dance, though Ayu dancing on top of a male dancer looked kinda awkward for her...
In the end my favorite pv from this album is definitely merry-go-round.
