Rebirth in the 80s: Starting a Business

("Second Male Lead" takes the lead, but it's a bit special)Song Shuyin transmigrated, transmigrating into a miserable woman. She injured the eldest son of the Cheng family, was utterly disliked by the Song family, and was sent to a remote rural area to suffer for two years. Just as she was about to return home, she died outside a cowshed.Back in the capital, because she was liked by the eldest son of the Cheng family, her entire family forced Song Shuyin to marry him. Helpless, she could only find ways to delay, but Cheng Daoyuan, the eldest son of the Cheng family, was a madman, pestering her relentlessly, and his words implied that he had known her for a long time. Both the Cheng family and the Song family were eyeing her covetously, as if they couldn't wait to plant a bomb on Song Shuyin's path to success. She could only forge ahead, but the longer she stayed in this book world, the more she felt something was wrong. Could this not be her first time transmigrating?
