I Haven't Fought Monsters for Many Years

Wen Aci transformed into a fake daughter among real and fake daughters. After the soft and cute real daughter came back, she was treated indifferently by her parents, her younger brother was disgusted, her classmates gossiped behind her back, and even the servants at home looked down upon her. She could only pack her bags and rent a house by herself, because her real parents had passed away long ago, and the real daughter had been adopted by the richest family in City H, and they looked down upon her even more. These—— It doesn't matter to Wen Aci! I can finally leave the endless horror battle royale world where I can't sleep all day long. I don't have to worry about being plotted by the people around me, and I don't have to numbly wield weapons to fight against deformed and terrifying monsters. Is there anything happier than this?
