As she stepped inside the Lockhart's territory, she started uncovering the secrets within that mansion.

A strange, unseen, and terrifying secret.

Will she be able to handle everything she discovers inside the mansion?

Can she stay in a place full of mystery?

Or will she be able to escape alive?

Will there be sacrifices needed for her to uncover such secrets? Or she'll end up as their pet?
