She is Cinderella at the bottom, and he is the cold and overbearing boss. The two people, who had never met each other before, started a journey of sadomasochism due to an unexpected encounter.
She was tenacious and struggled to survive in the darkness, just to find a glimmer of light. He was aloof, but fell deeply into her after meeting her. However, his love was mixed with possessiveness and selfishness, which hurt her completely.
When her life experience was revealed and she became the target of public criticism, he was shocked to realize that he could no longer live without her. However, it was too late to make amends. She burned out the last ray of light in the darkness, leaving him alone in sorrow and repentance.
This is a sadomasochism intertwined with love and hate. They dance in the darkness, but in the end they cannot escape fate and end in tragedy.
