I'm a villainess... it seems?! No, no, I'm not such a bad woman-!! Liz Beltran is an arrogant, selfish young woman, and a villainous one at that. When Liz arrives for her formal marriage meeting with the first prince, Alan, she is shocked to hear his younger brother's voice speaking to him. "What do you mean, 'villainess'? I'm not such a lousy woman!" She is shocked and teary-eyed, but her marriage partner, Alan, tells her, "I'll be your fiancé and help you out, so you don't end up becoming a villainess." She struggles to understand incomprehensible words such as "target" and "game world," but at the same time, she is thrilled by the too-sweet guidance of the beautiful Prince Alan as she strives to get back at the prince's brother! With the help of the prince who is "apparently" about to break off their engagement, Liz strives to become a perfect lady in this unique romantic comedy about a villainous lady!
