System: Womb for Womb

"On the first day of classes, my roommate gives me a crystal bracelet as a welcome gift. Without thinking, I quickly adorn it around her mother's wrist.In my past life, my roommate wanted to be a social butterfly. She was determined to have a hundred boyfriends by the time she graduated. But no matter how reckless she was, she never ended up conceiving.On the other hand, I kept getting pregnant and having countless miscarriages. But unlike her, I had never been in a relationship.The entire university mocked me, labeling me promiscuous and shameless.During my 66th miscarriage, I died on the operating table from severe bleeding. It was only after death that I realized the crystal bracelet my roommate gave me had somehow linked our wombs together.As soon as I opened my eyes, I realized I had gone back to the first day of the semester."
