A ONE is yet to be released but we already know that a new song called "Step by step" (not included in this album) will be the theme of the new NHK drama 「Beauty and boys」 starring actress Yukie Nakama !
No details about a future release at the moment !
Edit : This will be an up-tempo song with a strong positive message ! The drama will start on April 14 and will end on August 25 for a total of 20 episodes.
