Thirty-six-year-old painter Ye Xiangwan is trapped by Alzheimer's disease in the memories of her eighteen-year-old self, forgetting that she personally signed the divorce agreement. To protect Ye Xiangwan, Shen Jibai tears up the agreement and bears the family's humiliation and public criticism alone, concealing the truth with quiet restraint. One day, Ye Xiangwan suddenly awakens to the truth while reading her diary and falls into Shen Jibai's arms with a smile. Shen Jibai never marries for the rest of his life, remaining trapped in the art studio filled with memories of Ye Xiangwan's past. Decades later, an elderly Shen Jibai sits by the sea as the ocean breeze turns the pages of the diary on his lap. On the final page are the words: Love has never been forgotten.
