Once upon a time, there was an old cabin in the middle of the forest. For generations, the cabin had been passed down from ancestor to ancestor. An old woman named Martha inherited it and decided to live there for a year.

One evening, when she returned home, she found a strange book titled "The Man from the Window." Curious, she opened it and began to read.

The Rules:

If you hear knocking, ignore it. Go to the attic immediately and lock the attic door. If you don't, something will happen—but no one knows what. Be ready.

Once you're in the attic, do NOT turn on the lights. Find a cloth—it should be there somewhere—and lay it down gently. If you make even the faintest sound, he will hear you. There will also be a pillow, a blanket, and a pair of headphones. You will need them later.

If you find a chair, NEVER sit on it. It creaks and will alert him.

At all costs, do NOT open the window, no matter what. Even if knocking surrounds you, ignore it and put on the headphones.

NEVER open the attic door, even if you hear your loved ones calling for you. Stay silent, or HE will hear you. The headphones will help.

After reading the book, Martha scoffed.

"Ai, this is nonsense. I'm going to bed."

At 11:30 PM, she suddenly woke up to a tapping sound from the window.

Tap. Tap. Tap.

Her heart pounded. The book's warning echoed in her mind. Without hesitation, she hurried out of bed, climbed to the attic, and locked the door behind her—silent as a whisper. Her breathing became rapid, her hands trembling.

On the floor, she spotted a cloth.

"That's just like in the book..." she thought.

Remembering the rules, she carefully laid it down and stayed silent.

Then—loud, heavy footsteps thudded downstairs.

Her blood ran cold. Someone—or something—was inside the house. She clasped her hands together and prayed, her heart hammering in her chest. After a few agonizing minutes, the footsteps faded.

Her prayer had worked. But at what cost?

In the dim attic, her eyes landed on a chair in the corner. Next to it, a candle. A small sigh of relief escaped her lips.

"Finally, I can rest my back for a moment..." she whispered.

But just as she stepped toward it—a sudden jolt of fear stopped her.

A voice in her mind screamed: NEVER SIT ON THE CHAIR!

Swallowing hard, she backed away and curled up on the cloth. Exhausted, she drifted off into uneasy sleep.

Then—tap. Tap. Tap.

This time, it wasn't just tapping.

A voice followed. A child's voice.

"Gramma? Gramma? We're here! Mommy dropped us off!"

Martha's eyes widened. It was her granddaughter, Maya.

Her alarm started blaring.

But an hour earlier—before her "grandchildren" arrived—something else had spoken:

"Hello? Anyone there?" The monster had whispered, mimicking the voice of a child.

Martha wasn't that smart.

She opened the window.

THEN BAM.

The End of Chapter 1.
