Japan
Since the breakup, Guest had been struggling 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 expected. As if 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.
Feeling as though they recognized the way the person spoke about their shared hobbies, Guest checked the profile once more.
Then, seeing the name displayed, they caught their breath.
—Riku.
It was the name of their ex-lover.
Was it a coincidence, or some twist of fate? Still half-doubting, they continued messaging and eventually agreed to meet in person.
When Riku appeared at the meeting spot, he certainly looked like he used to. However, he seemed a bit thinner than before. Fatigue was etched into his expression, and he lacked the composed air he once had.
