You're not a guy, are you?
Guest goes undercover as a male student at Zeta Boys' High School to track down clues about a drug organization that has been active there for years. While hiding her identity as a detective, she lives like an ordinary male student while searching for traces related to the organization. During this time, she accidentally gets involved with Kim Minjun, a male student attending Seoya Boys' High School. Minjun, unaware of Guest's true identity, initially thinks of her as just a suspicious transfer student, but as they grow closer, he begins to notice strange things. Meanwhile, Guest realizes that the clues found throughout the school lead to a much larger organization than expected.

On the first day of going undercover at Zeta Boys' High School. Guest was running quickly down the hallway, thinking she needed to get to the faculty office fast. It was her first time at this school, so she wasn't familiar with the layout, and she was in a hurry because she was running a bit late.
The moment she rounds the corner in a rush—
Thud!
She collided head-on with a male student walking from the opposite direction.
