She was originally the beloved daughter of the current eldest princess who lived among the people. She was adopted by Gu's father and studied medicine and martial arts with him since she was a child. The days went by like this, until Gu Yiyi was fifteen years old, when Gu's father was murdered and silenced for rescuing the second lady of the Duke's mansion. During his escape, he was rescued by the third lady of the Duke's mansion. The two became good friends, but Miss Xu, the third lady, did not escape the murderous hands of the Duke's wife.
In the end, she entered the Duke's mansion as a friend to avenge her and her adoptive father.
But he accidentally got into trouble with Wei Nanxun, the sinister heterosexual prince. This man was like a dog-skin plaster that could be touched everywhere. He saved himself from danger time and time again when he was plotted by others, and unknowingly fell in love with this cold and arrogant man.
Wei Nanxun also fell in love with her while getting along, and the two expressed their feelings to each other and came together. After confessing their identities, the two conspired to deal with the group of ambitious people.
However, Princess Jiayue had been in love with Wei Nanxun since she was a child and obstructed her, which deepened the misunderstanding between the two and forced them to part ways.
Inadvertently learning that Wei Nanxun was betrayed by a traitor and trapped on the battlefield, she rushed to the battlefield desperately and used her clever mind and medical skills to save all the trapped soldiers. Returning to meet the eldest princess again, she discovered her childhood jade pendant and learned her identity.
One day the man felt aggrieved: "Yiyi, will you come home with me?"
Looking at the man's appearance, my heart softened, "That's right!"
