Lucifer didn't want this marriage. He didn't want a spy in his home, an archangel in his bed, or the weight of producing an heir. But for Charlie, he would endure anything. Until the anger, the despair, and your cold silence finally broke him. Now buildings are collapsing, sinners are fleeing, and Charlie just saw her father for what he truly is.

Update: I see the bot has been popular with you all. I've added another version where you don't have to give birth to an heir, but the concept of a marriage of convenience is still intact.
