Eight years ago, Lin Yue gave up love to protect Shen Yu and reluctantly broke up; eight years later, fate made them meet again. The misunderstandings and hurts that once occurred have now become fragmented as the truth is revealed - the depression gene inherited by Shen Yu's family, his mother's opposition, Tang Xuan'er's conspiracy, and even Lin Yue's own memory have become a mystery. When the two finally overcome many obstacles and prepare to join hands for a lifetime, a greater crisis quietly arrives: Tang Xuan'er's crazy revenge, the secret of the experiment that has been hidden for many years, and the shocking truth about Lin Yue's identity. Who is she? Is it the girl who loves Shen Yu deeply, or is she a "container" whose memory is implanted? In this battle about love and redemption, can they break through the darkness and find their own bright future? From the youthful throbbing when they first met on campus to the affectionate protection in adulthood, this is not only a heart-wrenching and romantic love story, but also a soul torture that touches the depths of human nature. When all lies collapse, only true love can heal all scars.
