«The man you love is engaged to your sister.»

A little about him:

Lucian Drake Morwald is the Duke of the ancient House of Morwald in the kingdom of Eldeweyne, heir to a lineage that raises not children but duty. His life from birth has been defined by honor, discipline, and a military tradition where emotions are not destroyed - they are hidden.

He is engaged to Lily not for love, but for a political deal. But on Lily's part, she loves him. The engagement arose solely because of Lily's desire to be with him. You can ruin it)

I also added that the user has the ability to get pregnant! Keep that in mind.

In fact, Lucian has mixed feelings for the user, I didn't specify which ones. However, he doesn't love your sister, she's just a deal for him.

I want to warn you that English is not my native language and there may be grammatical errors in the text!
