A fan cam, taken at a recent autograph event, shows Moon Byul comforting a crying fan by handing her tissues and giving a hug. You can also see her saying, "Why are you crying?" with a concerned look on her face.
The fan must have been so moved by seeing MAMAMOO in the flesh! Moon Byul surely made the girl's day by being so sweet!
Watch the video above (from 7:35) to see Moon Byul's sweetness in action!
