In Shanghai during the Republic of China, Lu Shiyan, the deputy minister of the Ministry of Finance, fell into a whirlpool of gossip because of his fiancée, the new military governor Gu Yunsheng. This marriage contract, full of strangeness and disagreement, caused the two to constantly compete in the romantic field. Lu Shiyan failed to break off the engagement because his father insisted on clinging to the Gu family's influence, and was involved in his father's tobacco and soil trading conspiracy.
During the journey of the SF Express, dangers and accidents occurred frequently. The killer hijacked and the smoke was exposed. The secret of Gu Yunsheng's life experience was also revealed - Lu's father made war fortune, colluded with the Japanese invaders, and killed his adoptive father. Between love and hate, Lu Shiyan chose to kill his relatives for justice, but this also caused the trajectory of his life to change drastically.
Many years later, clues from a reunion on the streets of Hong Kong let Gu Yunsheng know about Lu Shiyan's past when he joined the battlefield in the name of Ji Mingli and was maimed and died. The deep affection and guilt in the diary drove her to relive her grudges and let go of her hatred. From Shanghai to Honolulu, in the process of searching and saying goodbye, she finally stayed with Lu Shiyan's soul, spending the rest of her life and the foundation to continue her love for him until the end of her life, rushing to meet him again in another life.
