Overlord Fanfiction Crossover

Before my parents died, they arranged for me to marry Alan Palmer, the powerful but impotent overlord of Northingdale. The day I received the engagement letter, strange floating messages appeared before my eyes. [Don't marry him. He can't have kids, and he's violent!] [If you go through with this, that freak will torture you to death. Run!] [Your childhood sweetheart is your true love. Run away with him!] My childhood sweetheart, Leon Wade, grabbed my hand and looked into my eyes with what seemed like deep affection. "Tiffany, let's run away together. Have your maid take your place and marry Alan. She knows you well. No one will notice." Fooled by the so-called love in his eyes and those floating messages, I chose to go with him in my past life. I could only watch as the maid stole my identity as the heiress of the Glissons, gave Alan a son, and walked away with hundreds of millions of dollars in fortune. In the end, Leon held her in his arms. He tied a huge stone to me, kicked me into the ocean, and said smugly, "From now on, she's Tiffany. As for you, rot at the bottom of the sea forever!" I watched as sharks slowly tore into my body, pain ripping through every inch of me, until only my bones sank into the dark water. After being reborn, I finally understood that those floating messages were fake. They were carefully planted traps designed by Leon. Now, facing him and his pleas for me to run away, I let out a cold laugh and ignored the floating messages. "I'm not some helpless maiden. I'm marrying Alan."
