Nineteen-year-old Lu Zheng is the most dazzling young general in Daqi. She, Chen Yan, was the childhood sweetheart who grew up with him. Everyone said that they were brothers, but she was the only one who knew that the two of them had been inseparable for a long time. With heavy snow falling, he put on his armor and went out to fight, promising her a triumphant return. But there was an avalanche, and he fell into a deep valley. He was alive and dead, but his body was not seen. The imperial edict was issued, and the emperor granted her a marriage and made her the crown princess. Shen Yan resisted the order in public: If Lu Zheng doesn't come back for a day, I won't get married. Three years of cold and summer. She guarded the two elders of the Lu family, worked hard on her own business route, gritted her teeth and waited, rejecting all the glory in the world. In the darkness, the prince silently cleared away all the obstacles for her, speaking with deep affection and forbearance. Unexpectedly, at the end of the three-year period, news came from the border - Lu Zheng was back! However, the young general who returned has lost all his past memories. Next to him was a woman with great military exploits, Su Ling. It was she who saved him from dying in the Snow Valley. Lies were woven into the past and defrauded him of all his trust and reliance. The boy who used to protect her to the core now looks like a stranger to her. Su Ling regarded her as a thorn in his side, and she was constantly plotting and trapping her, hoping to get rid of her quickly. During the confrontations again and again, Lu Yan watched her suffer, and felt strange throbs in his heart. The memory is blank, but the instinct is always leaning towards the old person. Shen Yan was disheartened and planned to run away, no longer trapped in this old dream that had long been broken.
