Cursed sisters. A haunted castle. Two strangers with dangerous promises.

In Berhi Castle, Astina hides a darkness that threatens to consume her, while her sister Brillin roams the halls in a beast’s body. For eight years, they have trusted no one but each other.

Then fate delivers two outsiders: a silver-haired mage with a secret past and a reckless prince who proposes marriage at first sight. Both men promise freedom, safety, and even love. But every smile hides a secret.

As Astina’s heart betrays her and Brillin dreams of life beyond the castle walls, the sisters face an impossible choice: dare they trust these strangers? Or will opening their hearts shatter the only bond that has kept them alive?
