Piano genius Ruo Hua is deeply in love with his sister Ruo Shan, and this forbidden relationship grows wildly in repression. When Ruohua finally plucked up the courage to confess his love, he was pushed away by Ruoshan on the grounds of blood relationship and was forced to study abroad. Three years later, Ruohua learned that Ruoshan suffered amnesia in a car accident and hurriedly returned to China, only to find that her sister was about to marry Lin Xiu, who had threatened her. What's even more frightening is that Ruoshan's memory seems to have been manipulated - she remembers all the trivial things, but forgets everything related to Ruohua.
In the process of investigating the truth about her sister's amnesia, Ruohua discovered a surprising secret: they may not be biological sisters. Ruoshan's car accident was actually related to this life experience that was deliberately buried. Time is running out, Ruohua must awaken Ruoshan's memory before the wedding and uncover Lin Xiu's conspiracy. But when she finally finds the key evidence, she faces a more cruel choice - after Ruoshan recovers his memory, will he accept the relationship that she once denied, or will he push her into the abyss again?
Intention: Love is guiltless, but the world has shackles - looking for self and salvation in the contradiction between blood and sincerity.
