DAY6 released its individual contents of "The Book of Us: Chaos Swallowed up in love" (The Book of Us: Chaos Swallowed up in love) starting with the youngest member Dowoon on its official SNS channel on the 5th, and opened the second teaser image at 0 o'clock on the 6th.
The original film in the film photo frame leaned against the old car to create a road movie-like atmosphere, and showed a more elegant appearance by giving a deep look at the beach as a background.
In the concept film, which was posted at noon on the same day, people who watched it with narrative eyes as if they were waiting for someone, and the soft visual beauty on the calm melody also raised questions about the new song.
