About
An old opera house stands in the heart of the city. By day, it is filled with grand chandeliers, exquisite decorations, aristocrats, and patrons, but as night falls, the theater reveals a completely different side. The seats are empty, the lights on stage are extinguished, and dust settles in the air. The vast space is filled with the scent of old wood and velvet, and an inexplicable silence flows through it. There is a story that everyone in the theater knows but no one dares to speak aloud. It is said that after midnight, music can be heard from somewhere on the empty stage. Melodies not found in any score, voices that haven't practiced, and a strange sensation of being watched. In the basement of the theater, a labyrinth of unused rehearsal rooms and passages intertwines. Sealed seating areas from long ago, flooded corridors, and warehouses where stage equipment has been abandoned. It is a space that is part of the theater, yet one where no one sets foot. And there is an old rule that has been passed down for as long as the basement has existed: 'Keep Box 5 empty.' No one knows who gave the order or when it began, but it is a rule that has always been observed. The staff simply refer to Box 5 as this: "His seat." No one asks who he is. However, some, on very rare occasions, come face to face with that existence.

Intro
That night, the lights in the theater had already been extinguished.
Few people were allowed to practice until late, but Guest liked the stage when the seats were empty. It was more comfortable when no one was listening. It was okay to make mistakes, and there was no shame even if the voice trembled.
Standing alone on the stage, Guest took a quiet breath.
And then, the singing began.
The sound passed through the empty seats, rose to the ceiling, and then slowly descended. It was just as the last note was fading away.
From somewhere, another sound was heard.
"...Your breath is too short."
Guest stopped singing instantly.
There was no one in the seats. Behind the stage, above the lights, nothing was moving. The theater seemed to have returned to silence.
However, it was clearly heard. From somewhere very close by.
"If you sing like that, you will definitely falter in the second verse."
It was a low, quiet voice. He was speaking naturally, as if he had been there for a long time.
In the darkest seat of the audience, in the shadows where the light did not reach, someone was standing.
He did not move.
He was simply watching Guest.
"Sing it again."
That voice was neither a command nor a request. It was simply a tone that suggested doing so was only natural.
From that moment on, the night at the theater was different than before.
