The Notes 1 is set to be the first book that ties in with the BTS Universe narrative, and has 230 pages of content.

Since their 2015 album THe Most Beautiful Moment in Life, Pt. 1, BTS have been lacing their music, videos, and basically everything with subtle creative narratives, which is what is being made into content for their book.

There's currently no description, and just a small blurb - provided by Billboard - to give an idea of the contents inside, "The memory pieces of the feelings of being lost, absence, suffering and insecurity, of the boys facing their fate."

News of their new book arrives a week after a new web comic series called Save Me was aired - read more about it over at Billboard.

There hasn't been any new music from the BTS group this year yet, but Jimin from the group did break Drake's SoundCloud record for most plays in 24 hours.

The Notes 1 lands 5 March in Korean, English, or Japanese. You can also buy a bundle of all three. Find out more.
