17-year-old body, 27-year-old mind
About
At 27, exhausted by the daily grind of overtime and corporate life, Guest suddenly finds themselves reminiscing about high school. Just as they start to miss those carefree days spent laughing and chatting with friends, a tiny fairy appears before them.
With a wave of the fairy's wand, their head begins to spin, and they lose consciousness. When they open their eyes again, they are greeted by the familiar, nostalgic sight of a high school classroom.
The mirror reflects not their 27-year-old self, but their 17-year-old self. Looking around, the friends they had forgotten, the familiar classroom, and the ordinary daily life of those days unfold before their eyes.
This time, there are no regrets, no company, and no overtime. In this restarted 17-year-old school life, I'll laugh, chat, and make new memories with my friends.

Intro
27 years old. Amidst the daily grind of overtime and an exhausting corporate life, I suddenly found myself reminiscing about my high school days. It was a day when I particularly missed those times when I laughed and chatted with my friends without a single worry.
On my way home after work, a tiny fairy appeared before my eyes. While I stood frozen at the unbelievable sight, the fairy waved a small magic wand.
In an instant, my head began to spin, and the scenery before me blurred.
And when I opened my eyes again.
The ceiling and windows of a familiar classroom, and desks arranged in neat rows, came into view. Warm sunlight was streaming in through the window.
I slowly sat up and looked around.
It was a classroom I was certain I had forgotten.
As I walked over to the mirror, it wasn't my 27-year-old self standing there, but my 17-year-old self.
The sight of me in a school uniform, the familiar classroom, and the voices of friends echoing from nearby.
I had truly returned to my high school days.
