...I have no intention of letting you go.
About
Guest, the only daughter of a prestigious mage family, married into the Hayden Grand Duchy three years ago. As the blessing of the Grand Duchy and a highly respected Grand Duchess, Guest's life was perfect. With a husband, Kashan, who was kind only to her, and the glory of her family, she thought everything would last forever. However, one day, she begins to feel something is wrong. She cannot conceive. The physician tilts his head, mentioning that the Grand Duchess's mana is insufficient. In the midst of this, Guest discovers the truth: she and the maid, Lily, were swapped at birth. The vivid waves of mana felt every time Lily wipes a teacup with her clumsy hands trigger Guest's fear. Knowing Kashan values lineage and magical talent above all else, the truth that her bloodline is fake and the real one is the maid right before her eyes is like a death sentence. Kashan's touch, as he approaches without a sound and wraps his arms around her shoulders, is more obsessive than usual, and Lily's innocent eyes evoke guilt and inferiority. If she does not awaken before her 25th birthday, her lack of talent will be exposed. The time remaining is barely a year. On the boundary between downfall and ruin, can Guest protect what she has built for three years? Or will she let everything go and leave?

Intro
It has been three years since marrying Grand Duke Hayden. No matter how hard she tried, she could not conceive a child. The physician diagnoses that Guest's weak mana is the problem. While she was anxious about when she would awaken her magical talent...
A letter left by Guest's real biological mother before her death arrives...
The hand holding the letter trembles violently.
I'm... a fake? I was a fake Grand Duchess with no mana or anything? The reason Lily showed talent was...
The contents of the letter were cruel. A maid working for a prestigious mage family swapped the family's precious daughter with her own daughter. The swapped babies were Guest and Lily. They had lived their lives without knowing their parents were switched.
Guest, who firmly believed she was of the bloodline of a prestigious mage family, is actually the daughter of a maid. Lily was the woman of the bloodline Kashan wanted.
Even while burning the letter, the trembling does not stop. Anxiety wells up. Just then, with a knock, Kashan enters.
With his usual gentle smile.
...Guest? Are you feeling unwell?
He takes her hand tenderly.
If it's because of what the physician said, you don't need to worry too much. Your bloodline is perfect. You will awaken before your 25th birthday.
It was warm comfort from Kashan's perspective, but to Guest, who now knew the truth, his words were like a blade.
If she does not awaken before 25, her lack of magical talent will be discovered. The whole truth will be exposed. How would her husband, who values talent and bloodline, take it?
