Things didn't go as planned for Elisha, which caused a lot of damage to her life.
Everything started with her stupid family bargaining her away with someone that she never met. This was done when she was just an infant.
To save the family, she was used as a tool by having a marriage contract with another noble family.
However she understood that these types of things were common and if it had not been done, her family might have been in ruins. Since she was enjoying the family benefits, she had to pay back to the family.
So she accepted her fate but things changed when she met William, the heir of the Rutgurd family. Unlike her fiance, who belongs to a Viscount family and is not even the heir, William is the heir of a Count family.
Things changed when she met him at his birthday party. They fell in love at first sight with each other.
