Two days after the "2013 KHJ Show - Party People" fanmeeting in Seoul, Korea, KeyEast stated that Kim would be releasing his third mini-album Round 3 on July 22.[2] Before its release, they pre-released three photo teasers: the first photo teaser shows his back muscles with Korean traditional pattern tattoos,[3] the second photo teaser shows his intense gaze downwards with a tattoo on his neck,[4] and finally the third photo teaser shows him staring at the camera with intense gaze, but the focus is on his torso, which is covered with a clearer tattoo, particularly a Korean goblin, emphasizing the mix of tradition and modern sounds.[5][6] Jay Park and Dok2 participated in the lyric-making as well as featuring in the songs "Unbreakable" and "Your Story" respectively.[7][8] In addition, both songs were created by Steven Lee, who produced Kim's previous Korean and Japanese albums. Also, "Unbreakable" was choreographed by Lyle Beniga and directed by Hong Won-ki, while "Your Story" was choreographed by Keone Madrid and directed by Jo Soo-hyun.[4]
On July 15, KeyEast announced that Kim Hyun Joong's new song and music video "Unbreakable" would be released on July 18 at 12 noon prior to the release of the album.[9] Four days later, the "Your Story" MV teaser was released on July 22,[10] together with its other tracks.[11]
