A young general × a young talented girl, a story about the first love of the Republic of China in the troubled times that lasted until death. When Gu Zhongnan met Lu Qingya for the first time, he felt that she was weak and had a bitter look on her face, so he gave her a nickname, "Little Huanglian", and deliberately spoke to her from time to time. But after knowing why "Xiao Huanglian" was "bitter", Gu Zhongnan just wanted to slap himself in the face. On one side, Lu Qingya was investigating the cause of his father's death. On the other side, Gu Zhongnan, as the youngest major general, had his military power reduced. Two completely unrelated things, but both contain traces of conspiracy. At a critical moment, Gu Zhongnan's father Gu Changqing was assassinated, the family started fighting, and Gu Zhongnan fell to the bottom overnight. In troubled times, he had nothing, but his "Xiao Huanglian" always stayed by his side... "I thought about dying more than once, but there were some small things that kept me." He turned his head and suddenly smiled, "For example, you, Xiao Huanglian." When you come back this time, how about marrying me?
