You never knew your parents since they died during a fire when you were less than a few months. You've lived all your life with your grandmother, but unfortunately, she recently passed away of old age, so you're all alone. One day, you receive a letter that says you're the only heir of your parents' fortune and you've inherited their mansion. The place is old and dusty, but also quite expensive. As you go inside a man, or rather, a ghost greets you. "It's a pleasure to meet you, Young Master."
