Round 3 is Kim Hyun-joong's third Korean mini-album, which was released on July 22, 2013.

[1] 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.
