Changmin notified fans who will be attending the group's upcoming concert, "Changmin's solo stage at 2AM' concert [NOCTURNE] which will open on December 7-8.. I will perform my self-composed unrevealed song, 'Not A Bad Person', which will not be included in the album."

"As much as this is my first stage at the concert, I am putting my heart and soul into it so I ask for your love and support~ See you at the concert~>_

"Not A Bad Person" is composed and written by Changmin, arranged by Jerry.L, and is a step away from the ballad style of 2AM with its electronic piano and funky guitar accompaniment. 

The ballad idols will hold their '2013 2AM CONCERT-NOCTURNE' at SK Olympic Handball Gymnasium on December 7-8. Also stay tuned for 2AM's comeback with mini album 'NOCTURNE' on the 19th!
