DIA promoting Do It Amazing (2015)


In February 2015, MBK Entertainment announced its plans to debut a new girl group. Originally, the company had decided to have possible candidates for their new group compete on a reality survival program, through which the public could become familiar with the group members. MBK Entertainment revealed the first potential members to be Cathy, Eunjin, Seunghee, and Dani. Seunghee originally made her debut as member of F-VE DOLLS in 2013, however she left two years later when the group disbanded. The next three members to be added were Kim Minhyun, Moon Seulgi and Chaeyeon. However, Dani, Seulgi, and Minhyun later on dropped out of the project. Eunice was briefly a member of the group Jewelry, but never officially debuted with them before their disbandment in early 2015. Ultimately, by June MBK Entertainment had changed their plans, and decided to cancel the reality survival show and choose the members of the group themselves. DIA's members were formally introduced to be Seunghee, Eunice, Cathy, Jenny, Yebin, Eunjin and Chaeyeon.


On September 14, 2015, DIA released their self-titled debut album, Do It Amazing. On the same day, the music video for their lead single, "Waenji (Somehow)", was released. Their first official public appearance was also on September 14; the group performed a showcase at the Ilchi Art Hall in Seoul. They made their official debut stage on the music program M! Countdown on September 17, 2015.

On October 19, DIA released the music video for "Nae Chinguui Namjachingu", another song from their debut album, and they continued their promotions for this new song on music stages.
