[Game Description]

A disturbing truth lies behind a chance meeting. What awaits at the end is tragedy—or something worse.
And your choices are the only way forward.

• In a remote mansion shrouded in monochrome, unsettling silence creeps through the halls. Unexpected guests. Unwelcome events.
  And at the center of it all: you.

• Every decision twists the story further. One choice can doom a life—or save it.

• Prepare for a branching narrative with multiple endings—some darker than others.

[Story]

You are a model citizen, praised for your generous donations and tireless volunteer work.
One night, caught in a downpour, you’re helped by a stranger on the roadside.

That stranger leads you to a secluded mansion where several others have also gathered, seemingly by chance.
At first, everything feels strangely normal. Too normal.

But by morning, a cold corpse is found.
Who did it?
And why?

As fear spreads, you must uncover the hidden truth and fight to survive.
Trust no one. Terror may be closer than you think.
