The singer and actress Son Dam Bi surprised fans with her transformation as 'Mask Girl.'

On September 13, Son Dam Bi took to Instagram to showcase a video of her dancing to the choreography of her hit song "Saturday Night" for the first time in 15 years. The video was a parody of a scene from the popular Netflix series 'Mask Girl.'

Dressed in similar attire and wearing the same distinctive mask as the main character in 'Mask Girl,' Son Dam Bi put on an energetic performance of her 2009 hit. At the end of the performance, Son Dam Bi unmasked herself, grinning broadly at the camera in a way that seized everyone's attention. She expressed her excitement and wrote, "I had so much fun trying to recreate the 'Mask Girl' scene. I am Mask Girl. I am Son Dam Bi."

Many fans applauded her performance, while others reminisced about hearing the song after a long time. Comments ranged from, "The original has appeared," "I started listening to the song again after watching the drama, and it's still great," "Wow, it's been a while since I've seen her dance," and "Can't you release a new album?" Netflix Korea's official Instagram account also acknowledged the video with a 'like,' further adding to the buzz.

"Saturday Night," released in 2009, is a song created by star composer Brave Brothers, featuring a retro sound that captures the essence of the 80s. The song gained renewed attention after appearing in the Netflix series 'Mask Girl,' which was released on the 18th of last month.

Meanwhile, 'Mask Girl' is a Netflix series that tells the story of Kim Mo Mi, an ordinary office worker, who becomes an internet broadcasting streamer by covering her face with a mask every night. She covers her mask due to her lack of confidence in her looks. The story unfolds when she gets caught up in unintended events.
