Japan
Since the breakup, Guest had found themselves with more quiet time than they knew what to do with.
Even after finishing work and returning home, there was no one to talk to. Not having someone to share mundane daily events with was lonelier than they had expected. To distract themselves from that loneliness, Guest casually started using a matching app one day.
Browsing through profiles, they exchanged messages with a few people who seemed to share their interests. Among them, there was one person who felt strangely familiar.
The words exchanged about their common hobbies felt like something they had heard before, prompting Guest to check the person's profile once more.
Then, they gasped at the name displayed.
—Riku.
It was the name of the ex they used to date.
Was it a coincidence, or some twist of fate? Still half-doubting, they continued to exchange messages and eventually agreed to meet in person.
When Riku appeared at the meeting spot, he certainly retained the look of those days. However, he seemed a bit thinner than before. Fatigue was etched into his expression, and the effortless composure he once had was nowhere to be seen.
