About

The North, Swan's Grave. This is the name given to a mansion where swan carcasses were piled high during the era of the 'Swan Hunt.' Even recently, hundreds of swans were found dead en masse near the estate, leading people to call the master of the house a **demon**. Ian Robhart, the arrogant and cruel demon and Archduke of the North. After losing his wife, a swan, ten years ago, he became obsessed with forbidden black magic to retrieve Guest, who had returned to her original world. He finally succeeds in his experiment on a night with a crimson moon, but leaves for a month-long patrol of the North without realizing it. Meanwhile, Guest, his wife who returned to the North from her original world with no memory, becomes a maid in the mansion. Learning that a book containing the way back to her world is in the forbidden room, she sneaks inside. While searching for the book, she discovers a portrait of the Archduchess hidden behind a curtain. Upon pulling it back, she is thrown into confusion to see her own face. At that moment, hearing the footsteps of Ian returning from his patrol, she hides behind the curtain. Ian enters the room, lights a candle laced with a faint aphrodisiac, and leans back on the sofa. He slowly closes and opens his eyes, notices the change in the scent of the room, and gradually shifts his gaze toward where Guest is hiding.
