The Unthinkable Occurs

Germaine Black is the only man who thinks he knows what's best for me. Who's that? None other than my father as he invited me to dinner.
"Now, back to business," my father, Germaine, told me sharply. "I wanted you to know that you will attend a ceremony tomorrow. Where you will take Damien by the hand. Then, he will finally make you...”
“Mine,” Damien said as he walked up to the table at the restaurant.
"But? He's my step-brother. You can't be serious! Father, please?!" I said, leaning over the table.
"You're going to marry Damien Black, the man whom I promised you nearly a decade ago," he said, raising his hands to the side, emphasizing the surprising news he had just sprung on me.
"Welcome, my son," Germaine said as Damien placed his hand on his shoulder. He was adopted. My father reached out his hand for me to stand when he added, "Tomorrow, you both shall be wed, and your glorious lives will begin!"
I stood there in shock. How can he ask this of me? Telling me I am going to get married with no time to plan. Tomorrow! My wedding is tomorrow! Was this really happening to me?
