My Character Is the Wicked Female Supporting Lead

My adopted sister at home was sweet and obedient, the sort of girl everyone wanted to protect. Because of her, my boyfriend broke up with me. My brother hit me for her. Even my parents wanted to disown me. “Get out! We spoiled you rotten, and now you're cruel to the core. You're not fit to hold a candle to Tingting. Get out of this house right now! Tingting is our daughter!” Hah! I turned around and walked away without a second thought, selling off every last asset the family owned along the way. After all, I was the sole heir to the Shen Group!
