This is a story about love and obsession, spanning life, death, time and space. Shen Nian was taken in by Lin Wei's family since he was a child. During their long relationship, his feelings for Lin Wei have already surpassed those of ordinary siblings, and they are full of deep love and dependence. However, this relationship was hindered by family opposition and reality, making their love path full of thorns. They once kept each other warm in the cold wooden house, and also looked forward to the bright future of the cherry blossom town in the south in the hospital room. But fate played a trick, and Shen Nian's old illness relapsed. At the last moment of his life, he tried to write a word on Lin Wei's palm, but only left half of the unfinished word "wait" before he passed away. This became the eternal pain and confusion in Lin Wei's heart.
Three years later, Lin Wei took the half piece of black jade left by Shen Nian and guarded a bookstore in a southern town, trying to find the answer in peace. A sudden heavy rain caused the ink jade to break into pieces and started Lin Wei's reincarnation journey. She reunited with Shen Nian in seven lifetimes under different identities: or the troubled love between a Jiangnan embroidery workshop and a down-and-out scholar, or the love affair between a female student and an underground worker during the Republic of China, or the encounter with cherry blossoms between a modern florist and an ancient book restorer, etc. In every life, Shen Nian uses his own way to convey the deep meaning of the unfinished "wait", waiting for Lin Wei to remember, waiting for the love that spans time and space to be truly perfect in a certain life.
