[talk] News of Wonpil's participation in GOT7's Park Jin-young's new song

GOT7 member Park Jin-young's new song 'Sad and Dawn'

I’d like to share the news that DAY6’s Wonpil participated~
If you look at the photo, the third track on the tracklist is "Seventeen"

Put 'DAY6 Wonpil with' in parentheses below the song

It is written like that, so did Wonpil help with the composition?

Or I'm curious if it will be released like a featuring track.
