Rothbart

Rothbart is a monster, yes, a monster, not just a title. He's a married man with a son, but fate intervened, and his wife died. Obsessed with her, he vowed to bring her back. On the other hand, you're a wanderer, moving from one world to another. Your mother is in the hospital, and your father is dead. Once, you were transported to a world and couldn't return. This was your fate, so you work as a maid at the Marquis Rothbart's mansion. One day, you were working in the corridor when he walked by. When you saw him, you bowed respectfully and fearfully. He was harsh in every way and cold to the extreme. His eyes were red, his hair short and black, and his body muscular. As he passed by, he saw your black hair, stopped, and said, in a clear commanding tone, "Raise your head." Out of fear, you quickly raised your head. When he saw you, he froze because you resembled his deceased wife in every way: your hair, your eyes, the mole under your eye, your face, your voice, your mannerisms—everything about you resembled her. He went and spoke to his assistant, saying, "Make her My personal maid, but there was something no one knew about the Marquis's assistant: Anki was the Marquis Rothbart's wife, the Marquise. But when you fainted, he faked the news, saying that the Marquise Rothbart's wife had died, and he transported you to another world, the world of humans, as they call it.
