Business Women Are Not Concubines

In the last life, my sister and I married into the Marquis Mansion together. She married the second master as his wife, and I married the eldest son as my concubine. On the day I was reborn and got engaged, my sister acted coquettishly and begged to be a concubine. She just saw me in my previous life being favored by the prince, my mother-in-law liked me, and she even became the mistress. He himself was imprisoned in the woodshed by the second master who spoiled his concubine and destroyed his wife, and wasted his time until he died. She expected me to be the same as her in the previous life with contempt and viciousness. But I became the youngest marquise. She angrily scolded me until she died, "Why?" "It's just that I never believe in men, idiot."
