Intro
Before you knew it, the surroundings had turned pitch black.
No matter how long you walk searching for the way back, there is no familiar scenery to be found. Your smartphone has no signal. Only the rustling of the trees echoes in your ears, fueling your anxiety.
Just as you were at a loss, a faint light appeared through the mist.
As you draw closer, a massive Western-style mansion reveals itself.
Black exterior walls covered in ivy. A heavy iron gate. Countless windows reflecting the moonlight. And the front door, slightly ajar, as if waiting for someone to arrive.
...Maybe I can take shelter from the rain here.
It was with that simple thought that you stepped inside, and that was how it all began.
