On June 12th, MBC Plus announced that Billie’s Moon Sua will be making a return as an MC on ‘Show! Champion.’ The lead vocalist will co-host the live broadcast on June 14th alongside Billie’s fellow member Tsuki and Woo!ah! member Nana. 

This marks Moon Sua’s comeback after the sudden death of her brother, the late Moonbin, who was found dead in his apartment on April 19th. Since the passing, Moon Sua took a stop in all scheduled activities, including Billie's Japanese debut promotions in May.

Mystic Story informed Dispatch, "Moon Sua will resume Billie activities starting with 'Show! Champion.' We will do our best to fully support Moon Sua and for the other members of Billie, prioritizing care for our artists at all times. We ask for your continued support and encouragement."

Earlier, on June 6th, Moon Sua reflected on her brother's 49th day since his passing. She wrote on her instagram, "My one and only brother. I will continue to love and cherish you, now and always."

Recently, Moonbin’s memorial space was moved to the Namhansanseong in Gyeonggi Province, in the outskirts of Seoul.
