Eight years ago, she was a runaway little girl who was inexperienced, ignorant and reckless. He was a passionate young man who talked freely about new ideas with his friends. Eight years later, she is a singer in a theater. She looks weak and weak, but in fact she is resolute and courageous, capable of killing enemies with her own hands. He is a high-ranking young man who has returned from studying abroad. He seems to be as cold as ice, but in fact he is a tender and strong man who has the world and the heroine in mind. She is the young lady of the Jiang family who has replaced her friend who died of illness to recognize her ancestors. He is the eldest son of the Liang family who is engaged to the Zhang family. He taught for three years and joined the army for three years. He gradually matured from a teacher to a commander. In the peaceful years, she was his student; in the war-torn times, he was her patient. He died in the year when they were most in love. He held her hand tightly and said with his last breath: "In this troubled world, I have failed you in the end. I only hope that in the next life, the mountains and rivers will be safe, and that I will live in peace and happiness every year. I will live up to my love and your love!"
