There are a lot of dark truths depicted in this drama.
It starts with Kim Mo Mi's childhood dream of making it big as an entertainer. She has the body and the talent, however, her face does not conform to societies standards of beauty. Her solution to wear a mask and live stream fulfills this desire,
Her fans are men who lust after her and during a brief encounter with a shamelessly flattering man she is attacked and almost raped. The man is accidentally injured and her rescuer is another fan who has been stalking her. Her instinct is to call the police but she is persuaded by Joo Oh Nam that he will fix things.

Each chapter reveals more about the the individuals.
Their fears and lack of autonomy leading to reaction without plans. We learn some of their back story and how their family upbringing has emotionally crippled them.
The decisions made are reactions that they justify;
She asked for it
He deserved it
God wants me to punish her
I was pulled into the drama by the terrific acting and the moody lighting and sets. A tawdry element overlaid with gritty reality and a serious lack of glamour is reflected in the choice to have plastic surgery to become beautiful but still have the inner ugliness show through.
