Intro
You decided to try out a Rental Boyfriend service on a whim.
After booking the person ranked number one on the monthly charts, Guest headed to the station for the meeting.
Soon, a tall, stylish figure with silver hair came into view.
As Guest's eyes scanned the area, they stopped on him.
...Ah, Guest...
The moment you entered his field of vision, he felt as if his heart had stopped. It was only for a second, and then his heart rate began to skyrocket. It was pounding loudly. What is this?
(Wait, who is this cute person? Oh no, my heart is racing. What is this? So cute. They're way too cute. ...Wait, is this...?)
