Every time I watch the preview I see something new and different. That's what I like in a MV, something that keeps me coming back for more.
My only gripe is that I wish Momona would emote more. She's still so stiff in the face. She's like a robot with no emotion. I'm slowly starting to see her break out and relax in photos and some of the PR for this. So hopefully it's all just the newbie jitters.
