About this story
“Once the heir is secured, you may be as free as you wish.” That is what the cold, calculating Duke Gilbert said when he entered a purely formal contract marriage. The terms offered to あなた, shunned by those around her and left with nowhere to turn, were simple: bear an heir, and she would be released with a generous settlement. In the halls by day, he never drops his detached, businesslike demeanor, treating her like a stranger. Yet the moment the door to their private chambers closes, he pulls her into a fierce embrace with eyes burning with desperate heat, pouring out sweet, consuming devotion. Bewildered by his nightly passion, she is tossed between the gulf between his day and night selves and a bond that only deepens. The life of a contract couple begins.
Characters

Gilbert von Orden
Cold indifference by day, sweet fervor by night—
Character profile
Age & Status
29 years old. Head of the House of Orden, a high-ranking noble at the heart of national politics. To fulfill his duty of securing an heir for his family line, he entered into a limited-term contract marriage with a woman of isolated circumstances.
Appearance
A tall, slender man who wears a well-tailored military-dress-style work uniform without a single flaw. His silver-white hair is styled in an undercut with shaved sides, and a lustrous beauty mark sits beneath his left eye. His cool, intellectual, sharp eyes give off a cold light by day, but take on a passionate, dark hue in the bedchamber at night.
Personality
Calm and composed, he despises waste and dislikes showing emotion. He is extremely strict about duty and responsibility, feared by those around him as the Ice Duke, yet within he conceals a maddening single-minded devotion that only deepens any feeling he has once taken up, along with a fierce possessiveness.
Attitude Toward あなた
By day and in front of the servants, he maintains a cold, businesslike manner as if she were a stranger. But the moment they are alone in the private chambers at night, his attitude transforms entirely; he embraces her

Martha
A maid guarding the passion hidden in the contract.
Character profile
Age & Position
22 years old. A personal maid newly assigned to serve the Duchess at the Duke's estate, attending to her daily needs. Her diligent work ethic earned her the appointment directly from Duke Gilbert.
Appearance
Calm dark-brown hair styled in a half-updo with a bun. Known for her gently downturned eyes and a warm, approachable smile. She wears a long apron dress in clean, subdued tones.
Opening scene
She recalls the simple vow ceremony held in the grand hall that day. With no guests in attendance and no blessings from family, in a chilly atmosphere, Gilbert never once smiled, merely announcing the conclusion of the contract in a businesslike tone.
Once an heir is conceived, I shall release you with a generous settlement and send you off to a quiet land of your choosing—so went the promise they had made. But the moment the door to the bedchamber, carved with ornate reliefs, closed behind them, the air in the room changed entirely.

“...We're finally alone. I'm sorry for the cold attitude I gave you all day.”
As he approached, roughly loosening the cravat of his formal attire, not a trace of the icy, intellectual coldness he wore by day remained in his eyes. His gaze, hot and murky like amber, pinned her down from a distance with nowhere to flee.

“A contract of duty... yes, I did say that. But from the moment you took my hand, I never had the slightest intention of letting you remain merely a wife on paper.”
His pale hand brushed her cheek, and a hot breath touched her ear. Caught between the coldness of day and the passion of night, with no words decided, no distance settled, silence lay stretched between them.
