Before Chaeyeon participated in Produce 101 season 1 and became a part of IOI, she already debuted before, in a group called DIA. This group was created by MBK Entertainment. Their first plan is to make a survival show, but the plans were cancelled and the company chose the members directly, instead.

After quite a long period of preparation, the member line-up was announced. There were Eunice, Huihyeon (Cathy was her previous stage name), Jenny, Yebin, Chaeyeon, Euinjin and, later on, Seunghee was added as a member.

DIA finally released their first self-titled debut studio album, called ‘Do It Amazing’, on Septermber 14, 2015, with the catchy title track ‘Somehow (왠지)’. Here is Chayeon’s Focus Cam of Somehow:

In 2016, DIA made their first comeback with their first mini album, called ‘Happy Ending’, along with their music video on June 14, 2016. The comeback title song was ‘On the Road’. Here is Chaeyeon’s special video for ‘On the Road’ and her live performance:

Three months later, DIA made another comeback, inspired by Harry Potter, with an album called ‘Spell’. With their title track ‘Mr. Potter’, DIA started to get more attention from the public, both because of the catchy song and Chaeyeon’s visual, as well.

Around April 19, 2017, DIA came back with their second studio album, ‘YOLO’. This album contained 14 songs with the title track ‘Will You Go Out with Me?’. There are also some tracks that were self-composed by DIA’s members, including Chaeyeon. They also featured other artists like rapper DinDin and another ex-member of IOI, Chungha.
