あらすじ
Once a commoner, Wellmy Ernest ascended to nobility when her mother married an earl. She tormented her same-age half-sister at home and school, stole her heirship and fiancé, and finally sold her off to the allegedly cruel Lord of Magic. It's not like her plain, meek sister could oppose. Wellmy got everything she wanted. One day, Wellmy receives an invitation to a late-night soiree from the Lord of Magic, likely to announce her sister as his fiancée.
