Since the story takes place in the late 1990s, the K-drama will offer a retro office atmosphere. At the center of the story is Hong Geum-bo, who is almost 30 and has been working as a successful supervisor at the Financial Supervisory Service.

Geum-bo isn't just sharp. She's strong enough to succeed in the male-dominated workplace. Her life takes a dramatic turn when she uncovers suspicious financial transactions connected to a securities company.

To investigate further without drawing attention, she is assigned an extremely risky task: she must pretend to be a 20-year-old beginner employee and enter the company from the bottom level.

As her undercover mission begins, Geum-bo introduces herself as Hong Jang Mi, hiding her real identity. Much of her undercover work revolves around Dorm Room 301, the shared living space where she lives with young girls and tries to hide the truth from them.

Geum-bo's journey becomes complicated when she unexpectedly crosses paths with Shin Jung Woo, a man she had deep feelings for 15 years earlier. This reunion brings back old feelings and problems in her work.

So, will Hong Geum-bo be able to complete his undercover mission? Fans will find out soon!
