Shakoukai na no Dokufu to Yobareru Watashi - Suteki na Henkyou Haku Reisoku ni Ude wo Orareta no de, Sekinin Totte Moraimasu

Since childhood, I've always been good at understanding the atmosphere around me. So, when my half-sister, Marin, decided she wanted to be the tragic heroine, I willingly took on the role of the villain to please her. I had no other choice: our father, who adored Marin, would punish me by withholding meals if I didn't comply with her wishes. At tonight's soirée, Marin planned to capture the attention of Rio, the son of the Duke of Balgoa, from the remote territories. To help her achieve this, I was ready to follow her plan completely, even humiliating myself by pouring wine over my own head in front of everyone. I thought that would ensure everything went according to Marin's wishes, giving her the chance to get closer to Rio. But something unexpected happened; when Rio grabbed my wrist, I felt a sudden pain and heard a dull cracking sound. That dramatic moment marked the beginning of a new chapter in my life, as fate started steering me down a completely unforeseen path.
