Axi is a girl with a body unlike anyone else's, and rumor says her blood is so rare it can cure any illness. At a medical investment conference, Ye Zhiting, heir to a fortune and dying of an inherited disease, takes an interest in her. After Axi flees the conference, he tracks her to a remote village, brings her back to the Ye household, and gives her the name Ye Chenghuan. He means to use her only as a cure, but the more time they spend together, the harder it becomes to see her as one.
