Xiao Xiao was the adopted daughter of the Mu family and grew up side by side with Mu Tingshen as childhood sweethearts. Tragically, the two were abducted by human traffickers. To keep Xiao Xiao safe, Mu Tingshen lured the traffickers away from her.
Eighteen years later, Mu Tingshen has become the CEO of the trillion-yuan Mu Group, spending every single one of those eighteen years searching for his little sister Xiao Xiao. Meanwhile, Xiao Xiao lost her ability to speak after a high fever. She was adopted by another family and renamed Su Qian. Determined to track down Mu Tingshen, she traveled to Jinghai and took a job as a massage therapist.
By sheer coincidence, Su Qian is assigned to give Mu Tingshen a massage. The scene is witnessed by Qin Yuwei, a woman who is infatuated with Mu Tingshen, who immediately sets out to target Su Qian. Later, Qin Yuwei stumbles upon the jade pendant Su Qian wears and figures out her true identity as Xiao Xiao. She seizes the chance to impersonate Xiao Xiao, deliberately blocking Su Qian from reuniting with Mu Tingshen.
As a result, Mu Tingshen misses countless chances to recognize his real childhood friend. In the end, the full truth comes to light. Overwhelmed with endless regret, Mu Tingshen begs Su Qian to forgive him.
