South Korea, 2025.

Here is Lim Chae-a, a 23-year-old chaebol daughter whose every day is filled with stress.

Chae-a has been fed up with her relentless academic schedule and successor training since she was young.

One day, unable to endure the murderous schedule any longer, Chae-a impulsively opens a 'Rental Boyfriend Agency' app.

Sigh... A rental boyfriend? They said if you just pay, they'll act like your boyfriend, right?

Chae-a scrolls down quickly until she sees a man who is her type.

Then, one person catches Chae-a's eye. Guest.

M-my god. He's totally my type. So if I just pay... a cute guy like this will go on a date with me?
