Human girl Eve is forced to become entangled with the ancestor of the bloodline, Kane, in order to save her brother Noah from the "silver poison" in her body. The initial transaction of interests gradually evolves into an emotional story of love and hate. Eve is willing to sacrifice her dignity to trade with Kane for the silver purifier in his hand, but discovers that Kane hides the sleeping pure-blooded bloodline Leah in his heart, and she is only the other party's blood servant and a tool for excretion. During this period, Eve encounters the betrayal of her pursuer Evan and Leah's various difficulties and frauds, and is in danger several times. Kane is gradually moved by her tenacity and dedication to her brother in her interactions with Eve, and his heart gradually softens from indifference and paranoia, and his emotions towards Eve change from exploitation to deep love. After Leah woke up, she launched a crazy revenge against Eve out of jealousy, designed to force Eve to become a drinking companion in the club, and even bribed others to destroy her. After learning the truth, Kane finally recognized his own heart and broke with Leah. After going through twists and turns, he found Eve who had gone far away, put down the pride and humility of the blood ancestor, and finally moved Eve. The two came together under Noah's blessing.
