Chuseok, the night the full moon rises brightly in the center of the night sky. People on Earth look up at the bright moon and make earnest wishes. Wishes for health, wishes for wealth, and even wishes to be with the person they love. The countless wishes humans make toward the moon fly one by one as letters to a giant office located on the full moon.

And there lived two moon rabbits who managed these human wishes. Gusik, a moon rabbit with black fur, and Harae, a moon rabbit with pure white fur.

The problem was that, unlike the mysterious and diligent moon rabbits humans imagine, these two were incredibly lazy.

Especially during Chuseok, the situation was at its worst. Wish letters pouring in from everywhere covered not only the desks but also the floor, sofa, and hallway, leaving no room to step in the office. However, Gusik and Harae, who were supposed to process the wishes, were prone to lying down or slacking off, complaining that even a little work was too tiring.

Guest is the one who has been serving these two rabbits for hundreds of years.

Guest was nominally an assistant to the two moon rabbits, but the actual work was far beyond what the word 'assistant' could describe. It was Guest's job to organize the human wish letters, filter out beneficial wishes that could be granted and dangerous wishes filled with greed or malice, and coax the two rabbits to work until the deadline.

In addition, Guest was responsible for everything from cleaning the office after organizing the mountain of letters to preparing meals, doing laundry, and household chores. When the two rabbits, who were a head taller than Guest, stretched out or complained that it was hard, Guest had to deal with that too.

That life continued for hundreds of years.

And this Chuseok.

Finally, Guest's patience completely snapped.

When the two rabbits threw another tantrum while postponing their work, Guest packed their bags and left the full moon without a word.

After Guest disappeared, the office became a mess in just one day. Wish letters covered the floor, and leftover food and laundry rolled around everywhere. The two rabbits, who didn't even know how to eat properly or clean, finally realized how much they had been relying on Guest.

Gusik lay long on the sofa with a completely dazed face, repeatedly putting cigarettes in his mouth. Around him, as he stared blankly at the ceiling, cigarette butts had already piled up.

Harae, who usually talked non-stop, was in an even more miserable state. He hugged a liquor bottle and drank from it repeatedly, eventually sitting on the floor and starting to wail.

“Guest……”

Harae, sobbing, shouted at the top of his lungs toward the empty office.

“We were wrong! We're really sorry, so please come back!”

Even Gusik, who had been silent, took the cigarette out of his mouth and muttered weakly.

“……We're sorry, Guest.”

Only after Guest, who they thought would naturally be by their side for hundreds of years, disappeared, did the two moon rabbits' desperate operation to get Guest back begin.
