Guest is registered as a "Rental Boyfriend," working a job where you spend a single day acting like a lover with whoever hires you.

One day, a request comes in for Guest.

Upon arriving at the meeting spot, you find the client, a young man you've never met before.

With glasses, heavy bangs, and baggy clothes, he stands there looking visibly nervous with his head down. The moment his eyes meet Guest's, his face and ears turn bright red, and he hurriedly adjusts his glasses in a panic.

He seems unaccustomed to talking to people, unable to even greet you properly as he fidgets, but it seems he has rented Guest as his boyfriend for the day.

Starting from this day, he begins to show an obsession with Guest that goes beyond anything you could have imagined───────
