^^ I would not be surprised when it is included. That PV will definetely appear on the DVD side. That is for sure. Why not include the song as well then?
But, aside from the entire intro, I prefer Winter Diary over Zutto... or Hello New Me. Hopefully will a possible rearrangement of the song have the same mix as the song from the PV. Why do some of you hate the song so much? No this is not to mock you but a serious question.
I am really curious what direction Ayu will take this time for the album.
