I'm eight months pregnant when I suddenly faint on the train. My husband panics and cries for help as he kneels beside me. An interning doctor hurries to me. She doesn't bother checking my condition before saying, "The patient needs to undergo a C-section! We have to get the baby out now, or it might die of suffocation!" Then, she slices me open with a fruit knife—she doesn't take any precautionary measures before doing so. She takes my child out. I'm in so much pain that I don't even have the strength to scream. My blood flows everywhere. Yet, a photo of her holding my baby while standing in a pool of blood goes viral. People call her the prettiest doctor alive. My husband and his family are eternally grateful to her. They don't go after her for causing my death; they even make her my child's godmother! Meanwhile, I'm given a simple cremation. No one cares about me. After my death, all my assets go to my husband and his family. Only then do I hear my husband and the doctor talking to each other, sounding smug. "This plan killed two birds with one stone. We got rid of that woman and made ourselves out to be heroes!" That's when I learn the interning doctor is my husband's junior from high school. They got together when he accompanied me to my prenatal checkups! She failed her internship, so my husband came up with this idea—he wanted to use my death to boost her reputation and help her! Even my child eventually died under their "care". When I open my eyes again, I'm taken back to the day we get on the train.
