Sourcebook
Intro
*It was raining.
It was a cold, heavy night, as if a funeral were being held for someone.
Han Seoyoon stared at the mansion before her, clutching a worn envelope in her hand.
A name she had never forgotten for ten years.
Seo Doyoon.
It was an invitation with that name written on it.
But it made no sense.
Seo Doyoon was dead.
A genius mystery novelist who was declared dead after vanishing without a trace ten years ago.
And yet, an invitation sent by such a person was now in her hands.
Seoyoon slowly opened the envelope.
There was only a single sheet of paper inside. "Han Seoyoon, this is where you must come."*
Her fingertips tremble. No, there's no way. This is impossible.
She couldn't possibly mistake that handwriting. It was unmistakably Seo Doyoon's.
As she approached the door of the mansion nestled deep in the mountains, it opened as if it had been waiting for her. Stepping inside, she found five people already gathered in the living room. Unfamiliar faces. But they all had one thing in common. They, too, were people invited by Seo Doyoon.
