In a deep house in Shanghai during the Republic of China, they looked like masters and servants, but they met each other coldly every day and didn't say a single unnecessary word. In fact, both of them are undercover agents, and they are both responsible for saving the country. She knew that the road ahead was a dead end, and she was afraid that something would happen to him and ruin the overall situation, so she deliberately pretended to be cruel, broke up with him, and risked her life in exchange for information. He always misunderstood her and hid his love in indifference. Only when the incident was over did she realize that all her ruthlessness was to protect him.
Purpose: In the face of the righteousness of the family and the country, the love of children can only be tolerated and restrained; words of cruelty and alienation are all fulfilled silently. Even if they are misunderstood for life, they are willing to risk their lives to protect them.
