Artifact No. 13, or You'll Have a Thicker Horn!

How nice it is to unexpectedly receive a huge inheritance! However, my joy was short-lived, as alongside the mansion and a substantial bank account came artifact No. 13... And here I am in another world, owning a large house, fabulous treasures, and two dangerous handsome men. They bow to me and call me the highly esteemed lady witch, but I am just a simple girl. How can I not give myself away?
