He, Gu Huaizhi, is a 35-year-old army colonel and commander of a special operations brigade. Born into a military family, he is strict in running the army and has an almost rigid life style. He is regarded by his comrades as an "eternal iron tree" and an "ascetic male god".
She, Shen Nian, is a 28-year-old ancient building restorer and a doctor of Tsinghua University. Soft on the outside but strong on the inside, rich in spirit, always in the company of monuments, with a blank emotional experience.
A "ridiculous" marriage contract made by the grandparents forcibly bound people from two worlds. He saw her for the first time off the stage, and the sunlight shone on her through the broken caisson - that was the first freeze in his heart. They received their marriage certificate efficiently and rationally, just like signing a strategic agreement.
She started by knitting a woolen cover for his paint-off door handle, and used the patience to repair cultural relics to gradually change his deserted "single dormitory". He clumsily approached her world with weekly phone calls, handwritten letters, and detailed lists.
Until her birthday, he missed the appointment on the front line of flood fighting. She saw his muddy figure on the TV news, and all her grievances turned into heartache, and she drove to the disaster area. When he saw her in the crowd, he rushed over and hugged her tightly at all costs - at that moment, all the contracts became true.
Under the moonlight, he said: "Shen Nian, I got married before to complete my mission. But now, I want to be with you for the rest of my life."
This is a love story between two adults. There are no bloody misunderstandings, no deliberate twists and turns, only the pounding of the heart in the still water, and the two-way rush in the long time. He defends the country and she defends civilization. They shine on their respective battlefields and then become each other's light.
