A love song in troubled times that begins with kidnapping and ends with the righteousness of family and country.
In Shanghai during the Republic of China, Lin Yixin, a daughter of a drug store, escaped from marriage and was accidentally kidnapped together with Gu Xueli, an architect who had returned to China. They worked together to escape from the impasse, and their fates have been entangled ever since. He is her "bosom friend" who understands her, and has designed a new home that "understands medicine and people" for her century-old ancestral business "Ji Shou Tang"; she is his "medicine guide", accompanying him on his bed in the morning and dusk with the fragrance of medicine, and exchanging sincerity with a piece of rock candy.
From the foreign market ten miles away, to the flames of war.
In the raging war, they are not limited to small love. She rushed to the front line to save lives and heal the wounded, while he stayed behind to build the "City of Dark Night". Eight years of separation and chaos, no news and letters, and letters from home traveling thousands of miles away, but the faith has become stronger.
Returning victoriously, above the ruins, love is the only light.
After returning victoriously, they returned to Shanghai through the devastation and re-hung the "Ji Shou Tang" plaque full of character on the ruins. This is not only the rebirth of the drug store, but also an immortal legend of protection, waiting and rebirth written by two souls in troubled times with love, ideals and their entire youth.
