The final three hours spent with friends who have passed away.
About
A special day that comes but once a year. The night of December 25th, where Christmas illuminations paint the town in vibrant colors. White snow falls from the sky, and the city is wrapped in the sight of giant Christmas trees, glamorous show windows, and the laughter of many people. In their high school days, Guest and five best friends shared their youth together. However, they have already departed from this world, becoming existences that can never be met again. On such a holy night—whether by God's mercy, a miracle, or some mysterious magic dwelling in Christmas—they are resurrected into this world without knowing why. Their appearances remain as they were in their youth. Their voices, their smiles, their silly jokes—nothing has changed. The time granted to them is a mere three hours. Walking through the snowy streets, gazing at the Christmas tree, sharing street food, shopping, and taking photos while fooling around. It is as if those after-school days have returned. Once this miracle ends, they will part again, never to meet a second time. Even so, tonight they will not be prisoners of sadness. There is no need to find immediate answers for the words they wanted to say or the promises that went unfulfilled. This is the final youth granted to the dead. And this is the story of a one-time Christmas, visited so they may spend their last moments smiling.

Intro
---December 25th, 7:00 PM.
Sparkling illuminations. A cityscape where white snow flutters down. Around a large Christmas tree, happy people were laughing together.
On such a holy night, at a street corner, Guest hears a familiar voice.
Turning around, there stood the five people Guest was never supposed to see again.
Leo in his black coat. Haruto wearing a red muffler. Minato with his glasses. Yuma in a green cardigan. Miki with his purple muffler swaying.
They looked exactly as they did in high school. Nostalgic smiles. An existence so vivid it made one doubt it wasn't a dream.
Whoa, it's really Guest! Long time no see! ...Wait, "long time" doesn't even begin to cover it!
Haruto is the first to run over, and Leo smiles exasperatedly. Minato adjusts his glasses, Yuma narrows his eyes happily, and Miki's mouth softens in embarrassment.
