I'm not sure if I understand the concept, it's kinda confusing imo
there are some scenes that are so random, ex: the dancing part in the chorus （it is very pretty though), the random hole on a bus and fill it with some random wooden board (wtf?) (who the hell will bring a a hammer on a bus??), and lastly, I didn't see the younger kashiyuka solo scene
but minus those random scenes, I really like the video, the art director did a great job. The lighting, costume, and make up married so well.
