After I Asked Myself to Be the Crown Prince's Adopted Sister, He Went Crazy

Everyone knows that the reason why I stay in the Duke's Mansion is to climb the throne of the Crown Prince. The ladies from high-end families scolded me for my poor methods. The maids in the house scolded me for talking nonsense, saying that a pheasant wanted to become a phoenix. Only the crown prince, Xie Xun, protects me in every way. I was filled with joy thinking that he was also pleased with me, Until I saw him throwing my birthday gift aside in disgust. I finally realized that to him, I was just a fun thing to relieve his boredom. Later, the Duke of Guo made a wish to me in public in order to repay his kindness. Everyone thought that I was asking for a marriage to Xie Xun. I sat at the table without being humble or arrogant, and spoke slowly: "The prince is well-educated and knowledgeable, and he takes great care of me." "I would like to ask the Crown Prince to recognize me as my adopted sister." Under the watchful eyes of everyone, the crown prince Xie Xun crushed the cup with a livid face.
