Because I'm delusional. I tried looking through lists of songs of Johnny's groups. None of them has created a song fully by their group. Except NEWS. 6P NEWS. :) :D

Kinki kids has done it but like individually. One does the lyrics another will take charge of the song. Tegomass did it once. And also just wrote the lyrics as Tegomass once. But when it comes to doing a song together, no. And I just wonder, if it's really NEWS that came out with the song. If it is then it's really great because that means each one puts in effort for the song~
