[All] There's news that Cha Eun-woo appeared in a video letter of support on King of Mask Singer.

There's news that Moonbin's younger brother Billy Moonsoo-ah filmed a video letter to support his appearance on King of Mask Singer, saying that he takes care of and cherishes him like a younger brother.
