Which novel in literature is worth recommending?

I read a novel in junior high school and thought it was quite good. I still can't forget it and want to read it again. However, I forgot the name. I'm here to ask the literary emperor for help. Please tell me.
The novel went like this:
The novel should be written in the form of a letter. It should be the male protagonist's own story. The male protagonist was a member of the People's Liberation Army or the Eighth Route Army. He was in the hospital ward, telling the story, and the medical staff recorded it on his behalf. At the end of the novel, the male protagonist died.
It was about the revolution of our party. The male protagonist was still a child in the countryside. The female protagonist's mother seemed to be a teacher. She brought the little female protagonist to the male protagonist's home. From then on, the male lead fell in love with the female lead. This was when they were young.
He couldn't remember the plot clearly. It seemed that the male lead was shot by an undercover agent and told the story of his crush on the female lead in the hospital.

I believe that this novel will bring you a different reading experience. I hope you will like this fairy's recommendation.😗
