On March 5, 2010, 2AM revealed cuts of their new image through their official website. Jo Kwon, Changmin, Seulong, and Jinwoon respectively transformed to a club DJ, an ice hockey player, a biker, and a basketball player for their new 10 minute drama-music video. The repackaged mini album featured four additional songs, three from their first and second singles and one entirely new song titled "잘못했어 (I Did Wrong)", which was their promoted track. One representative stated, “The song we’re releasing is something that 2AM has never shown before and is a brand new type of music”. A portion of the song was revealed in the first episode of 2AM's new reality show 2AM DAY on March 10, where the members playfully sing along to it in the car.
