After Rebirth, My Sister-In-Law's Pregnant Belly Finally Exploded

In my last life, my sister-in-law was pregnant with ninth twins. I kindly advised her to have a smaller number of babies, and she finally gave birth to twins smoothly. The lazy brother and sister-in-law kept telling my nephew that I was the reason why they didn't become popular among men. In the end, I was killed by my nephew. I relived my life, avoided all problems, got married to my boyfriend, had a daughter, and lived a happy life.
