Because Su Xiaoya, a poor student, resembled Gu Yehan's "deceased" Bai Yueguang, she was forced to sign a contract to be her substitute, and she suffered from crazy possession. When she couldn't bear it anymore and wanted to escape, she uncovered shocking secrets one after another: Bai Yueguang faked his death to have plastic surgery, she was the real daughter of a top tycoon who was mistakenly carried away, and the gentle doctor Mo Jingshen who protected her was Gu Yehan's long-lost vengeful brother. Gu Yehan's obsession back then stemmed from mistaking Bai Yueguang for Su Xiaoya, who saved him when he was a child. After recognizing her ancestor and returning to her clan, Su Xiaoya dumped Gu Yehan, who was seeking to get back together, but was told by Mo Jingshen that she was pregnant with his child, and Mo Jingshen was the child's biological uncle. A bloody love dispute escalated.
