[Zhenbei General Chu Lin and Su Ruoruan]
Chu Lin, the general of Zhenbei, guarded the border with iron-blooded tactics, but accidentally rescued Su Ruanruan, a scholarly young man who was convicted and consigned to slavery. At first, Chu Lin thought that Su Ruanruan was squeamish, crying, and a troublemaker, so she only treated her as a casual help; Su Ruanruan was fearful of Chu Lin because of her majestic aura and was submissive to her.
During the relationship, Chu Lin was gradually moved by Su Ruanruan's thoughtfulness - he silently wrote down her favorite osmanthus tea, sewed clothes for her, and took care of the study room; when Su Ruanruan shed tears, he shed the general's coldness and compromising, and even made an exception to let him stay in the strictly regulated military camp. And Su Ruanruan slowly let go of her fear, regarded Chu Lin as her only support, melted her coldness with gentleness, and became Chu Lin's only comfort in the military camp.
As time went by, Chu Lin changed from "convenient care" to "exclusive protection" of Su Ruanruan. Su Ruanruan also gradually grew up under Chu Lin's protection. Later, she was able to overcome her timidity and stepped forward when Chu Lin was in danger. In the flames of war on the border and the daily warmth, the two ran in both directions to redeem each other, composing a heart-warming love song between a tough-blooded general and a soft-hearted young man.
