Kim Soo-jung

A woman asks her mother to leave for the sake of her and her brother’s happy life. But her brother does not open his mind to her. Although she gets closer to her co-workers at her new workplace, she has no choice but to become a disrupter of them. Without hope, her brother commits suicide in front of her. Her family members and colleagues have left her. Left alone, she dreams of life again.

Young-jin doesn't get a chance to get a promotion because she is a woman. On the other hand, Jun-seul easily gets a job as a manager with the power of connections.
