A Knock After Midnight

When Han Mirae moves into Ravenwood Colony, it feels like the perfect fresh start-quiet streets, polite neighbors, and a cozy apartment to call her own. But on her very first night, she begins to hear strange whispers through the walls and soft knocks at her door when no one is there.

Her enigmatic neighbor, Seo Jungho, offers her one chilling piece of advice:

> "Lock your door at night. No matter who comes... don't open it."

At first, Mirae brushes it off as paranoia. But as the days pass, unsettling things begin to happen-her belongings shift when she's alone, neighbors appear in places they shouldn't be, and she swears someone is watching her every move. Even her closest friends seem to be hiding something, their smiles just a little too perfect.

As the colony's dark history slowly unravels, Mirae realizes that nothing around her is what it seems. And the most terrifying part?
The danger isn't just outside her door... it's much closer than she thinks.
