The Fake Heiress Traded Her Daughter for My Son

After the wealthy family found me and brought me home, the fake heiress and I got married at the same time, and became pregnant at the same time. The fake heiress gave birth to a son, while I had a daughter who died young. I suffered severe bleeding during childbirth and could never have another child. From then on, I sank into despair, developed depression at a young age, and took my own life. Meanwhile, the fake heiress smoothly inherited the family fortune and took everything that should have been mine. Only after I died did I learn that the fake heiress had conspired with my family to switch our babies. Everyone had joined forces to deceive me, leaving me to die with unanswered questions. When I opened my eyes again, I was back before giving birth.
