It was released on 20 January 2011 by CNr Media and distributed by LOEN Entertainment.

The single album was originally planned to be released on 25 November 2010, but due to the rising tensions between South Korea and North Korea, Park and his company decided to push back his album release and promotions to the beginning of 2011.

[3] Park Jung-min joined hands with the star producer Shinsadong Tiger in order to create the single album.

Park is also involved in the album production as a lyricist.

From the title song "Not Alone" to "넌 알고 있니" and "내 하루는 매일매일 크리스마스", Park Jung-min personally participated in the composition of the lyrics.
