In the tenth year of the Republic of China, in Fengtian, Northeast China, Marshal Zhang Jingyao was handsome and enthusiastic, and he was a rare ray of sunshine in troubled times. Once he was ordered to go to the countryside and asked the long-retired former political figure "Mr. Tan" to come out to help his father. However, he met the old man's granddaughter, Tan Yin, who had a terrible scar on his face and a timid and low self-esteem.
Zhang Jingyao does not judge people by their appearance. He is attracted by Tan Yin's inadvertent revelation of talent, learning and kindness, and respects and pities her. Knowing that Tan Yin longed for new knowledge, he overcame everyone's objections and sent her to study abroad in the hope that she could break free from the shackles of her appearance. In France, Tan Yin met Zhou Jingzhi, a gentle and elegant progressive young man. Zhou Jingzhi's equal treatment and ideological resonance made her feel for the first time a friendship without pity from her peers, and she gradually regained her confidence. However, the huge secret hidden in her body is like a time bomb that may detonate at any time. Grandpa's teachings, his own beliefs, his increasingly complex emotions towards Zhang Jingyao, and the impact of new ideas brought by Zhou Jingzhi are intertwined. At the same time, the domestic situation was changing, and Zhang Jingyao was growing and struggling as he shouldered the important responsibilities of his family and country. When Tan Yin returns from school, his hidden identity gradually emerges. The fate of the three people is closely connected with the mountains and rivers of their family and country. The conflicts between emotions and the righteousness of the family and country, faith and reality are quietly staged... A love affair in troubled times that begins with humility and pity and ends with equality and perseverance slowly begins.
