The staff of "Show! Champion" held a moment of mourning for the late Moonbin, whose sister, Billie Moonsua, is currently serving as the show's host.

On the April 26th broadcast of MBC M's "Show! Champion," hosts Ua Nana and Billie Tsuki paid tribute to the late Moonbin, as his sister Moonsua was absent from the show.

Wearing black outfits to express their condolences, Nana said, "Last week, the music industry received tragic and sad news. Shining idol Moonbin, who had been an MC for 'Show! Champion,' has become a star in the sky." Tsuki added, "We will never forget and always cherish the moments that Moonbin gifted to us."

Moonbin had been an MC for 'Show! Champion' from March 4, 2020, until October 26, 2022. Moonsua took over the MC position, but has since halted her activities to take a break after the bereavement.

Meanwhile, Moonbin passed away at the age of 25 on April 19th.

On April 24th, Moonsua visited the memorial space set up at Fantagio's office and left a heartfelt note for her brother. She wrote, "Brother, it's me, your precious and one-and-only sister, Moonsua. I'm here to say goodbye. I cried so much, but I'll stop crying now. I'll smile a lot from now on. I'll do what I want and be happy. So please, be comfortable and happy there. You need to watch over me and see if I'm doing well. I'll live diligently for both of us, so don't stop me. If it gets tough, I'll come here often to act cute to you, so please accept it. You've been through a lot. I love you so much, and we'll be siblings forever. Moon siblings forever."
