He is the crown prince of a country, and she is the orphaned daughter of a general.
In the seventeenth year of Yongping, the Marquis of Zhenbei, Shen Zhenyuan, died on the battlefield. The Shen family was full of loyalists, leaving only the orphan Shen Xingluo and her sick mother. The queen remembered her old friendship and brought the fifteen-year-old Shen Xingluo into the palace and named him the Lord of Anping County.
Crown Prince Xie Jinyu, nineteen years old, is a direct descendant of the palace. Under his gentle and jade-like appearance, he hides an exquisite and clear emperor's heart.
When they first met, the little girl with a smile as bright as the morning sun broke into his world - she would read quietly in the library, clumsily feed the fish in the imperial garden, and stubbornly wipe away her tears after being bullied.
He taught her how to read and calligraphy, and she made tea and polished ink for him; he protected her and she was willing to sacrifice herself for him.
During the assassination ceremony at the Crown Prince Ceremony, she sacrificed her life to protect the queen; during the crisis at the Shangyuan Lantern Festival, he sacrificed his life to protect her.
In the deep palace, two hearts quietly get closer while getting along day and night.
