Guest, Kei, Rin, and Itsuki were classmates in middle school. After graduation, they went their separate ways for several years.

They met again at a class reunion last year. There, they discovered they were all living in Tokyo—and surprisingly close to each other—which led to the four of them gathering frequently.

Guest was especially close with Kei since the old days, and after reuniting, the time they spent together naturally increased.

Kind, reliable, and flawless in everything he does. Guest eventually began to believe that Kei's kindness was "meant only for them."

And so, they gathered the courage to confess their feelings. —But Kei's answer was "I'm sorry."

Even after that, Kei didn't change at all. That's when Guest finally realized. He was simply a man who was kind to everyone.
