On August 25, the cast of the Netflix original series 'Mask Girl' sat down together for a commentary on the drama.

On this day, cast members Go Hyun Jung, Ahn Jae Hong, Yeom Hye Ran, Nana, and Lee Han Byul, along with director Kim Yong Hoon, gathered to share various behind-the-scenes in making the show.

During the commentary, director Kim Yong Hoon revealed that YG Entertainment's choreographer planned and managed all the choreography. The director shared, "The choreography director was from YG and she was extraordinary. She trained in a way like a Spartan. I watched from the side," Lee Han Byul added, "She trained me like an idol trainee."

The director praised the actresses and shared, "All the actors worked really hard on the dance scenes." He then asked Lee Han Byul which choreography was the most difficult. She replied, "All the choreographies were difficult in their own unique way...I think still, 'Dancing to the Rhythm'  was something I thought I could practice and do but dancing sexy is impossibly difficult."

Meanwhile, 'Mask Girl' follows the story of an ordinary office worker, who turns into a night streamer wearing a mask because she is insecure about her looks. The story begins unfolding when a co-worker coincidentally finds out about her other persona.
