History
In late March 2013, T-ara's agency Core Contents Media were in the midst of forming a new unit from the group with the members Eunjung, Areum, Jiyeon and Hyomin. The unit's name, T-ara N4 (which stands for "T-ara Brand New 4") was revealed April 12, 2013. T-ara previously tried sub-units with the promotions of their sixth Japanese single "Bunny Style!", in which the B-sides were sung by units of two and three members; however it would be their first time official unit activities.

T-ara N4's debut single, "Jeon Won Diary" (전원일기; Jeon-won Ilgi), was inspired by the 1980s South Korean drama of the same name. Produced by Duble Sidekick, the song is said to have "funky and intense" dance music combined with elements of hip-hop, with the main motif of "Jeon Won Diary" about breaking away from the same everyday routine.

On July 10, 2013, Areum left the group to pursue her solo career. Core Contents Media announced that Dani would replace Areum's positions in T-ara N4 only, which Dani originally revealed to joined as the ninth member of T-ara in 2012 As of October 2014, their agency initiated Dani to not be part of T-ara N4 and would continued her training under the agency.
