Su Jinru, an ancient book restorer, and Lu Yunze, an upstart in science and technology, met in the modern city because of an ancestral jade pendant, but they were involved in a story of family secrets and the cycle of love and hate that spanned hundreds of years.
Su Jinru, a seemingly ordinary restorer, is actually the last descendant of the Su family, a prominent family in the Republic of China. He is burdened with the curse of "not surviving until the age of twenty-five" and can glimpse past memories by touching old objects; Lu Yunze, the cold and paranoid heir of the Lu family, whose family has been burdened with a century-old guilt and mission to protect the Su family, has a complicated purpose behind getting close to Su Jinru.
A jade pendant engraved with the word "cloud" became the link connecting the fate of the two people, and also revealed the bloody past of the Su family's extermination during the Republic of China. They got close to each other in sweetness and temptation, but they suspected and hurt each other because of family grudges and hidden secrets. The childhood sweetheart doctor Lin Shen looks gentle, but is actually a pawn of the forces behind the scenes; Mrs. Lu knows all the secrets, and her complicated attitude drives the relationship between the two.
From the entanglement when they first met, to the struggle on the edge of love and hate, to the exploration of the truth of the century-old curse, they found that each other's fate had already been involved in the closed loop of time - the young master of the Su family and the young lady of the Lu family in the previous life, and the Su Jinru and Lu Yunze in this life, were reincarnated in love and tragic death in each life.
When the curse shows its power and the conspiracy emerges, they must not only fight against the calculations of the third party forces, but also break away from the shackles of fate. Do you believe in each other to break the cycle, or are you swallowed by hatred and fear? In the intertwined tug of sweetness and sharp edges, they will eventually understand that only love and trust can become the glimmer of light that pierces the darkness and ends reincarnation.
