We’re in a Contract Marriage, But I’ve Imprinted

“We’ll be entering a contract marriage?”
Melissa, an omega and an illegitimate child of the Rosewood County.
Her only family and the only one who was ever on her side—her mother—had passed away.
“…This is not the Count’s funeral hall.”
“I couldn’t be certain because your pheromones were too light, but it’s true. You’re an omega.”
At that point in her life, Melissa was about to become the wife of an old marquis. It was a sacrifice she had to make for the sake of her family.
However, Ian appeared in front of her and gave one final choice that she could make.
“The contract’s main stipulation is very simple. Give birth to an alpha who will become the household’s successor.”
The contract marriage that began as such was like a sweet, sweet melody.
Knowing that one’s life was about to be devoured, but nonetheless addicted to that sweetness—unable to escape.
