Extras Don’t Want To Be Overly Obsessed

I thought I am just a one liner unnamed commoner extra. Until the villainous duke, who is known to kill every town he get into, came in to light and is in pursuit of a single young lady. “Duke Cedric is already halfway through the Empire. I heard he's coming to this area this month.” Why is the bloody duke is looking for his youngest sister who disappeared five years ago? “Rose hair and golden eyes.” That sister's description is the same as mine. I think my life is ruined. *** I then became the young lady known to be the youngest child of a villainous duke who is planning to kidnap and detain the heroine. After this, I am going to live like a calm water silent flowing and will run away. Because I didn't want to get involved in this crazy political drama in this damn novel. But… why is everything so weird? “Our Amelle, you don't look so happy. Do you want me to buy an island and build a villa for you?” My first brother, who kills people in normal day, is so impatient to give me something. “Our baby, can you just throw that away and live with your brother. I think I don't like being a wizard better than I thought. Isn't it?” The second child, who left the house ten years ago to become a wizard without any hesitation, came back again and keep himself attached to me. “Don't turn your eyes on the other one, Amelia.” Even the world's worst villain, who decreased the population of the continent in half in the original story, is interested in me. “I'm sorry, gentlemen, but I'm taking the Young Lady with me today.” No, even the heroine, whom I should kidnap, is kidnapping me instead? All these humans must be crazy. I'm just an extra. Would you mind getting away from me please?
