Reborn: Unmasking My Sister, the Fake Heiress
I had returned to the day when she had schemed against me.
In my previous life, my sister, in her pursuit of becoming the sole heiress of the family, resorted to scheming on the day of the school anniversary. She tampered with my fever medicine, causing me to lose consciousness. She took away my prepared speech and went on stage to deliver it, receiving all the glory.
Meanwhile, she led me to a secluded alley where I was sexually assaulted by a group of people. They even recorded the incident and posted it online with the caption, "The so-called heiress of the Xander family is nothing special."
