It's Future Boy's NOW, a remake of Fin.K.L's NOW.

It was a sudden(?) remake, wasn't it? I was surprised.

I was surprised that they remade a song by a female idol senior.

Anyway, this song is a real masterpiece.

The arrangement is also well done, so it seems like it was made well without any sense of incongruity.

Future Boys' unique choreography was cool, too.
