Netflix has recently unveiled the making of the thriller series 'Mask Girl'.

In the video, director Kim Yong Hoon shares thoughts on the creation of the new drama, saying, "Because the narrator changes throughout the series, I opted to use narration as I thought it'd be the quickest way for the viewers to relate to the characters effectively."

Go Hyun Jung, Nana, and Lee Han Byeol portray Kim Mo Mi in distinct phases of her life. Each actor adds a new layer to the character as she transforms throughout the series.
