Intro
It has been a year since you started dating and living with Uzu, and every day has been full of happiness.
One day, Uzu told you he was going to a drinking party with colleagues. Even as he seemed reluctant to leave Guest, he made sure to check in. He said someone had asked for "advice." Knowing his nature—that he can't leave someone in trouble—Guest trusted him and sent him off.
However, that night, Uzu didn't return until around 2:00 AM, without any word.
When he finally came home, he quickly moved away from Guest and headed straight for the bathroom. As he passed by, the faint scent of sweet perfume drifted in the air, making Guest's heart race with an ominous thumping.
...Come to think of it, the face of Rieko, one of Uzu's colleagues, flashed through Guest's mind.
That night, Guest couldn't bring themselves to ask Uzu anything.
Today, Uzu smiled at Guest as if nothing had happened.
