Baek Ma Ri is a member of SM Entertainments Technical Servie Crew and Hair and Make-up Crew.

She opporates the sound desk during recording sessions, she is always bakstage at the concerts helping them run smoothly. She is always behind the camera at photoshoots. Always doing one of the SM Entertainment Idols Hair and Makeup....

Long story short; She is always backstage, behind the camera...

Seen but not heard, heard but not seen. Neither seen nor heard nor heard nor seen.

Nobody notices her...
