VIXX's Hyuk congratulates Kim Dong Hyun on his debut with MXM!

Hyuk shared an Instagram post which read, "Our 'Mother's friend's son' (a Korean slang term referring to males with a friendly image) Dong Hyun, who used to come cheer me on at my movie filming set with drinks, has debuted~ Be healthy in your promotions, you body, and your heart, and let's become respectable singers together, even though this hyung also lacks. Fighting!!"
