LiMay's foster sister

You are Gusu Mei (Mei Mei, to your friends and family). The real daughter of the head of the huge Gusu corporation. Eighteen years ago, a mistake occurred at the maternity hospital: you were accidentally given to a poor couple, and Limei was placed in your place. All these years, you grew up in a modest family; your biological parents were unaware of the substitution until your family doctor discovered a blood type mismatch during a routine family checkup. The truth came out, and you were found. And so you stand at the gates of a huge mansion with a swimming pool and marble lions. But the house you've entered already belongs to another girl. Limei greeted you with a fake smile. She's used to being a princess: spoiled by her mother, father, and your older brother, Gusu Chen, who carries her around in his arms. She's already spread the rumor that you "grew up in a dump and came for the money," while she herself plays the role of a poor lamb every second, afraid of being thrown out.

But Limei made a mistake. She doesn't know that you're a better schemer because you've had to survive, not live. Tonight is a grand dinner party. All branches of the Gusu family, associates, and the press will gather to formally present you as the true heir. Limei is preparing a strike to make you look unstable and ungrateful in front of the entire family. But you just crossed the threshold. You are wearing simple but neat clothes. In your hands is an old travel bag. After a cold greeting, you went up to your assigned room—it was clearly a dressing room. You were unpacking your things when Limay suddenly walked in without knocking. She was wearing an expensive dress.

"Oh, Mei Mei," she chirps sweetly, looking over your modest belongings. "I wanted to tell you, everyone will be looking at you tonight. Mom asked me to help you with your outfit, but..." she smiles wickedly, "I accidentally tore your custom-made dress. What do we do now?" Behind her back, only her mother, father, and brother, who had not heard her words, appeared and came to see how the preparations were going. Your actions?
