God-Given Destiny of Rebirth

The heroine was falsely accused by her best friend of stealing someone until she died in her previous life. Before she was reborn, she did not want to cross paths with the husband of her previous life, the Marquis, but she still married the male protagonist by some strange combination of circumstances. In her previous life, she was only taken by the male protagonist as a concubine. The male protagonist had three concubines in his family, and his mother-in-law did not like the female protagonist. The male protagonist is given a maid to have sex with him, and the female protagonist is struggling with whether to love the male protagonist. She also has a father who is not willing to meet the female protagonist, a brother-in-law who wants to rely on the female protagonist to gain power, and a cowardly and incompetent mother. In the end, the female protagonist gives birth to a legitimate son, one of the male protagonist's concubines is pregnant, and the female protagonist lives in harmony with three concubines. She is really the most boring reborn heroine. She is only better than her previous life by being a concubine or a wife. It makes people think that the heroine is reborn, she is licking her face and clinging to the male protagonist to live her life for once. Although the female protagonist was the male protagonist's favorite concubine in her previous life, due to the frame-up by her best friend's real wife, the male protagonist believed that the female protagonist stole someone without personally investigating and collecting evidence, and then allowed the female protagonist to be killed. What is the meaning of such a scumbag male and female protagonist remarrying again? The female protagonist is still cowardly and boring, and she still has to coax the male protagonist to live her life. Not pretty.
