^^me neither. I mean these results are really surprising. But it seems Days is on its way to be one of newer Ayu-classics. I like Days. And I think the love for MOON/blossom is just because it is so recent and fresh in peoples mind. I doubt it would get this high in a few years. Especially the Cover.
But if they really love it so much, I'm the complete opposite of the japanese, because I think MOON/blossom is the most boring single she ever released.
