But she discovers that the marquisate has already adopted a girl to take her place. The fake heiress is adored by her parents and brothers, and even stole her fiancé. Everyone assumes she grew up poor and uncouth, and will grovel for their approval.

She deftly resolves every trap and misunderstanding with reason and force, winning many allies and becoming a welcome guest among the capital’s powerful and influential. What’s that?

My former fiancé is kneeling in repentance and begging to marry me? Xie Mianmian clings to a jealous, sickly, madly possessive beauty: I only need His Highness! Make him leave, now!
