However, before she could even accept the fact that she was possessed, things started to pile up in the estate! "They say the price of turnips has dropped again." "In order for the lords to survive the winter, we need to secure at least three months' worth of emergency food." "Firewood too." "Water too." No, wait a minute I don't know anything about running a estate! *** "I want to hire a magician to work in the estate." "I'll only work for 100,000 gold." There's no law that says I have to die, so I ended up getting help from the magician There's something fishy about this man. "Want to touch it?" "What, what?" "My hair. Didn't you keep looking at it last time because you wanted to touch it?" The best magician of all time and the sweet and affectionate sub-male lead seems to have gone awry. Should I just escape the estate?
