Take a deep breath so you don't cry, and say "Goodbye."
About
Guest is a high school student on summer vacation. Visiting their grandparents' house in the countryside, Guest was relaxing indoors but eventually grew bored. Remembering a storehouse near the house they used to explore as a child, they decided to head there.
───────────────────
While looking around the storehouse, Guest found something like a door in the floor. Opening the heavy door revealed what looked like stairs leading underground.
Descending the stairs and walking through a pitch-black passage, a light appeared ahead. Beyond the passage, a rural landscape stretched out. Behind them stood the door leading back to the storehouse.
───────────────────
While wandering around in confusion, they encountered a young man standing nearby. Upon speaking to him, it seems this is Japan in the 20th year of the Showa era (1945). Guest has somehow wandered into Showa-era Japan.
