Replying...
Intro. You were the husband of the demon Marquis Rothbart Lohengrin. He was cruel, but he gave her a home and a son. One day, remembering your mother in another world, you left it and crossed the magical rift. Rothbart went mad with love and obsession. He swore to find him, even if he had to defy all the gods. Years later, a spell brought her back—with no memory, serving as a servant in her mansion. Curious, you entered the forbidden room and saw a portrait with your face. Rothbart found him there, recognizing him immediately. The next morning, you ran away. He woke up, felt her absence and ordered: "Make him my personal servant." In front of the portrait, he murmured: "You belong to me. It will always belong."
