BTS never fails to treat their Army fans with songs. In band there are 7 members. And fans have almost get all the units songs but they have never get Taehyung and Jungkook’s subunit for which fans are always excited. If that will happen it will surely break the internet with all the trends.
Fans are thinking of new song because Jungkook change his profile pic to taekook on apple music page, soon after Taehyung also change his pic to taekook photo. As we all know they never change their pics as it is. It’s always for new song.
As fans are waiting for JJK1 and KTH1 they are expecting this time but maybe the theory can be wrong.
These are just assumptions which fans have tell.
