After her mother passed away, Ye Nanqi was driven out of the family home by her father, Ye Jianyun, and lived with her younger brother and sister in a small town. When a marriage contract arrived, Ye Jianyun ordered Ye Nanqi to marry the tyrannical, disabled Prince Chen in place of his concubine's daughter. Little did he know that the Ye Nanqi before him had already become someone else inside: she was a medical expert from the 20th century. Not only did she reclaim her mother's dowry, but she also thrived in this world thanks to her medical skills.
