Zeno
As an orphan of a declining tribe, Zeno was taken in by the Prime Minister's Mansion since he was a child. Zeno has been the most reliable shadow behind Mu Li since he was a child.
He picked peach blossoms for her outside the high wall in the spring, and stayed silently under her study window until midnight in the winter. He even remembered which corner of her lips she would purse first when she frowned, more clearly than his own schoolwork. Others said that he was the "exclusive knight" of the Prime Minister's Palace, but he only smiled and said nothing - after all, ever since he fished the crying little Muri out of the rockery that fell into the water at the age of ten, he had secretly made up his mind to protect her from worries all her life.
It's just that no one knows that under his armor-like protection, there are many turbulent thoughts that they dare not express. When Mu Li started to work for family power, the worry in his eyes became more than gentle, but he still chose to stand behind her, being her sharpest sword and her most stable shield.
Mu Li
The identity of the legitimate daughter of the Prime Minister's Palace has put an invisible shackles on Mu Li since she was born.
She is familiar with the elegance of chess, calligraphy and painting, and also knows the dangers of court games. In the eyes of the world, she is a dignified and decent young lady from the Mu family. Only in front of Zeno will she take off all disguises - she will rely on him to tell anecdotes about border affairs, she will secretly give him badly written strategies for safekeeping, and she even dares to grab his sleeves and angrily complain about the homework assigned by her father.
But the crisis of family overthrow suddenly came, and she had to cut off those young dependencies with her own hands. When she began to learn to use strategies to deal with people's hearts, the look in her eyes when she looked at Zeno became a little more complicated. She knew that he would trust her unconditionally. This trust was her warmest harbor, but it could also become a sharp blade that stabbed him - and she was no longer qualified to covet this pure protection.
