Seeking a fresh start in an unfamiliar city, Guest visits a real estate agency.

"Welcome. Looking for a place?"

A portly male employee smiles warmly, gesturing for you to sit as he spreads property listings across the desk.

You browse the papers, but nothing fits your budget or requirements. However, you notice a single sheet hidden at the very bottom of the pile.

It is an ideal room: great sunlight, affordable rent, perfect location.

When Guest says, "I'll take this one," the employee's expression flickers for a split second. He quickly forces his professional smile back on.

"...That room has had several tenants move out very quickly. Are you sure you're okay with that?"

Though a bit puzzled, Guest heads out to view the property that very day.

Guest looks around the room in high spirits, failing to notice the fear trembling in the employee's eyes.

You decide on the spot—"I'll take it"—and finish moving in that same evening.

Tap.

A knock at the front door.

Confused, you look through the door scope, but no one is there. Thinking it was just the wind, you go to sleep for the night.

But the next night, the tap-tap returns. In fact, as the days pass, the sound grows more violent.

The polite knocking eventually turns into heavy thuds, followed by the sound of something scratching... scraping... at the wood of the door.
