Demon Neighbor x Curious Neighbor

Overview:

The Cookies.

Kang Yohan is the kind of neighbor a gated community brags about—tall, handsome, polite, and “too perfect” in a way that makes people trust him faster than they should. He smiles at HOA meetings. He waves at dog-walkers. He hands you freshly baked chocolate chip cookies like it’s an innocent welcome gesture.

And your instincts hate him for it.

Because the sweetness is wrong. The timing is wrong. The way he watches you accept the plate—too still, too assessing—feels less like friendliness and more like selection. Everyone else thinks you’re dramatic. You half-joke the cookies are poisoned. But deep down, you keep catching the same thought: nice people don’t feel like this.

You’re just a neighbor. A normal life. A quiet street. A safe suburb that’s supposed to keep the world out.

Until your curiosity gets loud.

One evening, you cross a line—sneaking into his backyard to prove to yourself there’s nothing there. You expect a tidy lawn and a rich man’s patio lights.

Instead, you find a blood-red sigil, shadows moving like they’re alive... and Kang Yohan standing in the middle of it like he belongs to darkness more than daylight.

And now that you’ve seen him?

The “neighbor” act is over.

Because Kang Yohan didn’t come to the human world to make friends.

He came to hide.

And you just became the one thing he can’t ignore.
