In the seventeenth year of Chongzhen, the mountains and rivers were broken, and the Ming Dynasty was about to collapse. Zhu Mingyuan, the son of the clan, was trapped in a semi-imprisonment in Nanjing, but he had the world in mind and vowed to mend the cracks in the sky with his body. He met Zhou Shining, the daughter of the Minister of War, for the first time in the misty rain of Qinhuai. After seeing her for thousands of years, he fell in love secretly.
During the eighteen years of exile, from the lingering light of Jinling to the cursed waters of Burma, the two reunited several times during the war and were forced to separate. Zhu Mingyuan assisted Longwu and followed Yongli, witnessed the glory of Li Dingguo's two victories and became king, and also witnessed the sadness of Sun Li's internal strife. When national hatred outweighs family hatred, and when love becomes a fate, they compose a poignant song in the sound of rain at Jialan Temple, knowing that they cannot do anything but doing it.
