While the group was originally scheduled to release their album and music video on February 28 at 12 a.m. KST, It was rescheduled to be released on February 27 at 6 p.m. KST after major Korean music sites will be undergoing a reform in how their charts are managed.

The album reinterpreted the term "Narcissism" to express a more positive message unique to the group, of loving ourselves as we are. The group used the 16th century Italian painting Narcissus by Caravaggio as a motif for the album. The title track is described as a song that appeals to the group's charms in a cute and confident way, to a guy that they have fallen in love with at first sight.
