I'm not sure which novel you're referring to. However, based on the information you provided, I can deduce that the possible name of the novel is 'Wen Ruyan'. The female lead of this novel was called He Xi. Her family was all soldiers and she had a first love boyfriend. The novel told the story of He Xi and her family's life and experiences in the army, as well as the story of their reunion ten years later. In the end, the novel ended with He Xi marrying her first love and continuing their ten-year story.
