Oshiro's Secrets
It's nothing major, just some stories from the past.
At the end of the year, Guest was brought by family to visit a certain village in the mountains. It was a place more developed than one would expect from a 'village,' with sophisticated scenery and a dazzlingly beautiful snowy landscape stretching out everywhere.
After dropping off your luggage at the hotel, you decided to take a short walk. It's winter break, after all; you have to make the most of it.
After looking at a few buildings and walking for about twenty minutes, you saw a shrine. Passing through the bright red torii gate and entering the grounds, you heard people's voices.
