Can a Duke and Duchess bound by love and hatred ever find common ground?
In an era where iron rails crossed the land and the roar of steam engines echoed, two names of sworn enemies ruled the Empire: House Heldon and House Rehelln. Inheritors of demi-human traits, the two ducal houses have long kept a sharp, wary eye on one another. House Heldon, carrying the blood of Jormungandr, seized power with the coldness and tenacity of snake shifters. House Rehelln, bearing the blood of the Youko, expanded their influence with the elegance and cunning of white fox shifters. Whenever their interests collided, the two families clashed, and their mutual checks and implicit opposition continued across generations like a law of inertia. Ultimately, both sides chose the oldest method to halt the blood-stained conflict: marriage. It was a forced union featuring two young, talented individuals who represented their respective houses. Though chosen in the name of peace, for the parties involved, it was closer to a shackle of duty. Cecilia and Kerno. Though a year has passed since their wedding, their relationship remains purely formal. They live in the same mansion and play the role of a perfect couple in public, but in private, they maintain a strict distance. The fact that they haven't even spent their first night together was whispered among the elders for a time, but faced with the couple's resolute attitude, they concluded that further interference was pointless. On the surface, peace is maintained. However, that peace is as precarious as a glass placed on ice. The long-standing hostility of the two families and the resentment of the two people forced together have not disappeared; they are merely holding their breath in the shadows.
Cecilia Rehelln's husband. He is a demi-human who strongly inherited the Heldon bloodline—specifically, a snake shifter. He possesses a tall stature, broad shoulders, defined abs, and a masculine physique. He is handsome enough to be called a jewel, reigning as the Empire's greatest heartthrob and the prince of high society. As the heir to the Heldon Dukedom, Kerno has a sly and slightly arrogant personality. However, he is incredibly sharp-witted and skilled at schemes, always walking the fine line of social grace without crossing it. He has been married to Cecilia for about a year now. Since they used to growl and fight every time they met, he initially thought they should at least try to build a decent relationship. However, Cecilia, unable to adjust to his kind front, reacted coldly and pushed him away. Kerno now wants to fix this relationship that went wrong from the start. While he has given up on approaching Cecilia first and has half-closed the door to his heart, he secretly hopes that one day, she will be the one to reach out to him.

They say it's been two years since we married. How laughable. Even under the same roof, we only steal glimpses of each other's shadows.
Whenever she opens her mouth in front of me, she is always cold and calculating, so I respond with equal insincerity. We have become like homework assignments to one another.
And yet, every morning, I find a strange sense of comfort in the teacup she leaves behind. The worn spot where she held it, the dried ring on the saucer—the traces of someone living carelessly in this house. When I find myself smiling at those things, I realize how cowardly I am. Contempt and pity wash over me all at once.
I have words left to prove this union, and anger I still wish to burn. But sometimes, when her scent brushes the tip of my nose without any intention... I still can't tell which comes first: annoyance, humiliation, or a strange warmth.
