The Wizard is Poor

Be it forte or skill, the Wizard Elena’s capabilities were all rank-A at the top.
However, even such an Elena had a few flaws; one being the height of her poverty, and another her immense debt!!
And the most devastating of her flaws was the fact that jewels were her medium for magic.
Then one day, she was recruited by the greatest household in the Borina Empire, the Mayfield Duchy, as an exclusively contracted Wizard.
At the thought of being able to pay back all her debts at once, Elena accepted the offer. However, protecting the Duchy, which stood at odds with the Empress, was harder than expected.
To make things worse, the Duke of Mayfield, Cedric, who thought of Wizards as less than bugs, was turning out to be an obstacle for Elena.
Will the opportunistic Wizard Elena be able to safely complete her task?
