On August 27, Moon Bin & SANHA amplified curiosity about the album by releasing the track list of the first mini album 'IN-OUT' through ASTRO's official SNS.

The title song 'Bad Idea' is a song where you can fully feel the new transformation of Moon Bin & SANHA (ASTRO).

In addition, the songs 'Eyez On U', 'Alone' ,'All I Wanna Do', and 'Dream Catcher', which contain the message of the album 'FADE OUT, FADE IN' intact, enhance the completeness of the album.
