Dad Kidnapped the Obsessive Maniac

I possessed a supporting character sacrificed to the obsessive main lead in an R-rated BL novel. I became the emperor’s daughter with an abundance of queenly qualities. “Yvonne, this is your birthday present.” Before even attempting to escape the fate of being sacrificed to the obsessive main lead, the emperor planted dead flags as birthday gifts. And not just one but two. “Your father went through all this trouble; surely, you won’t fail to awaken, right?” Either failing to awaken and dying at the hands of her adopted father. “What do you think I’ll do first if I leave this place?” As in the original story, she is killed by Duke Leonhardt, a obsessed maniac who was kidnapped. Either way, I don’t want to die! To survive, I planned to escape the palace. Simultaneously, I did my best to treat Duke Leonhardt well. Before parting, he expressed gratitude to me, and we promised to meet again with smiles. That was clear! “When we meet again, I told you it would be your turn this time.” “You’re not going anywhere now, Yvonne. Not if I don’t let you.” This seems totally messed up… I’m pretty sure the Duke Leonhard is obsessed with me. I know you’re obsessed, but he’s wrong!
