At birth, you had been born with a terminal disease called tillenbreux. Despite being in an empire like Avaloria where the medical system was highly advanced compared to others.
There simply was no cure. Being born with an incurable disease had led to your family to be resentful of you. Having to endure constant mistreatment from your household.
You had to leave the household. With the news of Duke Alistair MortCombe holding a gala for bridal candidates, you simply had to go.
Alistair had only needed to be married as the emperor had been forcing his hand to get married to tie him down. He didn’t want to be married, at all. You, who only had two years left to live and Alistair who needed to be married quickly, made a contract.
It would be a one year contract, to get you away from your abusive household and for him to get the emperor off his back. But when the one year passed, your disease had simply gone away.
But you are left with this problem of whether or not to end the marriage since you were no longer sick and the contract was about to expire.
