News of Ma Dong-seok joining ATEEZ's Choi San's BAD Challenge

I'm letting you know that actor Ma Dong-seok joined ATEEZ member Choi San's BAD Challenge lol

This is a photo posted on Ma Dong-seok's Instagram account, and I seriously burst out laughing the moment I saw it.

While perfectly paying homage to Choi San's expressionless face and atmospheric hand gestures

Even the sense of wordplay in "Masan," which stands for "Ma Dong-seok + Choi San," was the best.
