The girl selling goods at the market had never seen money before.

In a world where academic success is paramount, a young girl ponders the extreme decision of undergoing sterilization to focus on her studies, but her parents refuse to consider it. A mysterious figure, Bai Jinxuan, intervenes, offering a solution that seems too good to be true. With a no-nonsense attitude, Bai Jinxuan convinces the girl that the procedure is necessary to achieve academic excellence, citing the example of a high-achieving student who has undergone the same procedure and takes additional medication to maintain their grades. Despite initial reservations, the girl agrees to the procedure, only to be surprised by the relatively low cost of 500 yuan. However, Bai Jinxuan's cryptic response suggests that the true cost may be more complicated than initially meets the eye. As the girl embarks on this unconventional path, she must navigate the consequences of her decision and the true nature of Bai Jinxuan's intentions.
