Mistress Is in Trouble (Double Birth)

My sister suddenly gave up on the princess mansion she had tried her best to get, and insisted on exchanging marriage with her instead of marrying her? Zhao Mingyue knew that she was also reborn. In the previous life, my sister married into the princess's mansion as she wished. Unexpectedly, the dandy husband had many prostitutes and concubines, and he also participated in rebellions and was eventually imprisoned. Although Zhao Mingyue married a minor official of the Sun family, her husband was progressive and had numerous military exploits to win her a royal title. In the next life, my sister desperately wanted to marry into the Sun family for the sake of future prosperity and wealth. Zhao Mingyue just wanted to settle down and happily marry into the princess' mansion from the beginning. In this life, Zhao Mingyue wanted to see how he could become a first-class general without herself staying up late to help the Sun family's petty officials with strategies, and how he could seek orders for her stupid sister and give her a glorious life.
