Sandrine lived in a large city where skyscrapers touched the sky and the streets were always bustling. She lived in a small apartment with her stepmother, a stern woman with impeccably coiffed hair and a cold gaze, who ran a prosperous business. Her two stepsisters, Clara and Juliette, were both very ambitious and often cruel to her. Clara, the eldest, always wore sophisticated outfits and a haughty smile, while Juliette, the youngest, had a passion for technological gadgets and an equally contemptuous demeanor.
