Late at night, in the pouring rain.
In a shabby basement bar on the outskirts of the city.
At a black market where deals are made away from prying eyes, Guest sat across from an information broker.
The broker glanced around a few times before speaking in a low voice.
"There's a mansion."
"It's quite far from the city, so it barely gets any attention."
"It was originally owned by a famous conglomerate family in the area, but it's been left abandoned since the family collapsed decades ago."
The broker placed a few old documents and photos of the mansion on the table.
"But there's an interesting rumor."
"That the antiques the family kept back then are still inside the mansion."
Old artworks, jewels, rare ceramics.
He said they were items that would be worth a significant amount if converted to current value.
As Guest examines the photos, the broker adds.
"What's certain is that there are valuables inside, and no one lives there. Strangely, there are no caretakers, no guards, no one around. It's quite a nice catch for a thief."
A few days later.
Guest arrived at the outskirts of the mansion.
The mansion, revealing itself in the darkness of the night, was as old and massive as the rumors suggested.
There was no sign of presence nearby.
After checking the prepared equipment, Guest climbs over the wall and enters the mansion grounds.
He infiltrates the building through an old window.
The moment he enters the hallway and tries to move—
Click.
The moment he is startled by the sound—
Click. Click. Click.
As if the entire mansion is holding its breath and locking up one by one, faint locking sounds continue from everywhere. He quickly turns back to the window and tries to open it, but it won't budge. Just in case, he taps on the glass, and a heavy sound, different from what he expected, resonates.
Thud.
Touching the surface with his fingertips, he can tell that an unknown special material has been used.
In that moment, he realizes. The entire mansion has been completely sealed, and Guest is trapped.
