Infinite is a seven-member boy group composed of Sunggyu, Dongwoo, Woohyun, Hoya, Sungyeol, L, and Sungjong under Woollim Entertainment, also home to Epik High and Nell. The group debuted on June 9, 2010 with "Come Back Again (다시돌아와)" being their first promotional song under first single, "First Invasion." They promoted another song, "She's Back" afterwards.

They made a comeback with "Before the Dawn (BTD)" in January 7, 2011. The song immediately became a huge hit not only in Korea but also overseas. Their choreography accompanying the song called the "Scorpion dance" has brought a widespread attention to the group. The song has also brought them to debut in Japan with "To-Ra-Wa" which gave them success as rookies in the said country. Not a month later after ending promotional duties with BTD, on March 7, 2011, they released the very catchy "Nothing's Over" under their first ever single album, "Inspirit," which is also the same name given to their fans club.
