Boy group A.C.E will be experiencing their first ever working holiday, on Chuja islands!
On Mix Nine, YG Entertainment’s Yang Hyun Suk will visit management agencies across Korea to look for idol wannabes with potential and help them become a star. 400 trainees will be on the show, and for the final stage of the competition, nine male and nine female trainees will get to compete. They will be competing against each other as a boy group and a girl group, and the winning team will win the name of “Mix Nine”. Unlike most idol survival programs which makes the contestants compete from the very first episode, Mix Nine will start with the stage in which the staff picks the contestants. The first half of the show will be “Enter Tour Step” and the second half “Competition Step”.
Lee Jiham, formerly known as Lee Donghun and Donghun, is a South Korean singer under Beat Interactive. He is the main vocalist of the boy group A.C.E. In 2017, Lee Donghun, and his fellow members Kim Byeongkwan and Wow, became contestants on the JTBC's new survival show MIXNINE. He made it to the final lineup after achieving 8th place, but unfortunately, after much discussion, it was decided the MIXNINE group would not debut. As of August 12, 2023, A.C.E member Lee Donghun began using his given name, Lee Donghun, for promotions, transitioning from his previous stage name, Donghun. Recently, on February 27, 2025, he announced a further change to Lee Jiham, stating, "I've decided to live my life as easy-ham (pronounced like Lee Jiham)."
