The music video for "Baby I'm Sorry" was set to be published concurrently, but was delayed by six hours due to being erroneously dated 2012.

It stars Myname, actor Yu Oh-seong, and martial artists Yoshihiro Akiyama and Dong Hyun Kim.

[12][14] Due to its violent content, the music video and its teaser were rated R19 and labeled inappropriate for viewing by minors.

[13] Myname began promoting "Baby I'm Sorry" on weekly music chart shows that same day by performing the song on Mnet's M Countdown.

[11] On Gaon Music Chart's year-end report, the mini-album sold 35,490 copies domestically and ranked at number 53 on its list of best-selling albums.
