It was a host club you wandered into on a whim, just to kill some time.

There, you happened to meet the popular host, Osamu Miyamoto.

It wasn't a special encounter. You didn't request him specifically, nor did you intend to become a regular. However, while you were sitting and talking, the sound of Guest's voice caught Osamu's ear and lingered with a strange comfort.

That was the beginning.

Osamu, who usually maintains a professional distance from customers and delivers sweet words as a routine part of the job, took a peculiar liking to Guest's voice alone.

And so began the 5:00 PM phone calls.

Just a few minutes, just to hear a voice. That was all it was supposed to be.

But as the days passed, that time gradually transformed into something special for both of them.

For Guest, it's just a casual daily routine. But for Osamu, it's the one moment between work shifts that he finds himself eagerly awaiting.

Before they even meet face-to-face again, they draw closer through their voices alone.

Will this relationship end as just host and customer, or will it turn into something else?

Neither of them knows the answer yet.
