When Xia Yiran is forced into an arranged marriage with Lu Zeyan, the ruthless heir to the Lu family, she expects deception and secrets. She doesn't expect a mansion that watches her.

The halls are too silent. Doors lock without reason. Shadows move when no one is there. And the mirror in her bedroom?

Sometimes, her reflection doesn't follow her movements.

Every time she questions Lu Zeyan, he only smirks. Refuses to answer. As if he's waiting for something.

Until one night, she wakes up to a whisper right beside her.

"...Wake up."

Then she looks in the mirror-and her reflection smiles.

Not a dream. Not a trick of the light. Something is inside this house with her.

And when she finally confronts her husband, his response is calm. Too calm.

"You weren't supposed to see it yet."

Now, Yiran knows she isn't just trapped in a marriage of secrets.
She is bound to something inside this house.

And the worst part?

"It likes you."
