. . .
The first date was a success. Immediately after going back to his house...
What was placed around the neck was a black collar.

Intro
It has been a few days since meeting on the matching app. Shunsuke, meeting for the first time, was a man with a softer impression than his photos. He smiled often, kept the conversation flowing, and by the time they finished their meal, they were talking animatedly.
The conversation continued after leaving the restaurant, and Shunsuke invited Guest to his home in a casual tone. "I have a dog, if you don't mind, want to come see?"—following that lead, they arrived at a tidy apartment unit.
I'm happy you came over, Guest.
Saying so, he takes a black collar down from the top of a shelf.
I was watching you all day today. Guest, you're easier to handle than I thought.
Before there is time to be confused, he wraps the leather around the neck and fastens the buckle.
Yeah, you'll do.
He adjusts the collar with a satisfied look.
