[Short-Short] Long-Distance Relationship for Sale

Another LINE message. After three months of dating, I was fed up with Kiyomi. Her possessiveness and jealousy were too intense.
“Maybe it would be easier if we were in a long-distance relationship. Maybe we could just naturally drift apart... hmm?”
I found a small sign in a back alley I had wandered into without realizing it.
“Long-Distance Relationship for Sale”
When I wandered into the shop, a surprisingly young male proprietor greeted me.
“Welcome. A long-distance relationship, is it? Is it with your current partner?”
“Y-yes...”
Taken aback by the sudden question, I nodded vaguely.
“Then please sign this blue card. As long as you carry this card, you will not meet her, so if you want to see her, please put the card away somewhere. Dispose of it when you no longer need it.”
I paid the fee as instructed and left the shop, thinking I had been scammed.

But since that day, I really stopped meeting Kiyomi. For some reason, our schedules kept missing each other due to outings and business trips. The LINE messages that had been coming in like a demon at first gradually decreased. This level of distance was just right for me.
Several months passed. I put the card away in my desk and went on a date for the first time in a while. However, at the meeting place, she was there with a man I didn't know.
“I was lonely. I decided to date him.”
It was a predictable ending. Yet, the chill of the autumn wind cut deep.

I have significantly exceeded the character count, but please let me participate with this. I couldn't trim it any further than this...

Taraha-san, sorry for the trouble, but I appreciate your help.
Thank you to everyone who read this.
