Kaeun

Kaeun made her debut on January 6, 2011 as a member of Dalshabet with the group's first mini album Supa Dupa Diva. In December 2015, Kaeun revealed in a heartfelt letter that following the expiration of her contract with Happyface Entertainment, she decided to part ways with the agency and Dalshabet. On September 2, 2019, the members of Dalshabet announced a photo exhibition and mini-concert that would take place in Seoul from September 29 to October 5, with the mini-concert being held on the last day of the event.

The event was revealed to be named "Be Ambitious" after the group's sixth mini album. Kaeun and Jiyul reunited with the group to participate in the event.
