My mother was once my father's favored concubine, akin to a secondary wife in old China. During childbirth, my eldest sister deliberately delayed calling the midwife, resulting in my mother's tragic death due to complications. After my sister became the Princess Consort, she told me, "A true sisterhood means staying by each other's side forever." I knew she intended to keep me close, tormenting me for a lifetime. Then, someone reached out to me, offering a lifeline: "How about I become your pillar?" I smiled, and that was when my sister's peaceful days turned into her own living nightmare.
