So-young (a woman in her 20s) succeeds in getting a job at a major corporation that everyone envies, but gets caught up in an episode of leaving her bag behind on her first day. One day, two days... and before she knows it, she's in her second year. So-young has adapted to a soulless corporate life where she bursts into laughter unconditionally at her boss's words. She should be living a happy life while working at a company everyone envies... but she has become a typical office worker who relieves the stress of her unhappy life by meeting her close childhood friends for a drink. While returning home after having a drink with her friends, So-young makes a huge mistake while drunk... and earns the hatred of Jonathan, who could offer her a life-changing favor.
