In a small city, there is an old house no one goes near.

An entire family vanished inside it twenty years ago.

No bodies. No blood. No trace.

Only one room on the second floor... its window never closes.

And every night, a faint light comes from it.

Then it disappears.

Then it returns.

Three friends decided to break the rule.

One of them went in.

The others... heard his voice from inside the wall.

"We did not disappear. We just can no longer leave."

This is not a story about a haunted house.

This is a story about a place... that does not let anyone who enters leave.

Read it if you dare.

But if you hear three knocks on the glass... do not turn around.
