In the twelfth year of Yongping, Lu Huai, the second son of the Marquis of Wu'an, enters the capital. He is ostensibly assigned as Crown Prince Li Jingxing's study companion, but in truth he is a hostage.
The hostage is frail and scholarly, with nothing but a handsome face. The young crown prince has never thought much of him, until the day he is defeated in battle and trapped.
Alone and without help, an arrow suddenly whistles through the clouds, driving away the gloom before dawn. In the faint morning light, a figure clad in white robes and silver armor charges out of a sea of blood and stops before him.
In those amber eyes are the vast ranks of an army, along with tender affection. Like an arrow piercing the clouds, they shoot straight into his heart. From then on, he can never forget.
As a boy, Lu Huai entered the capital alone, concealing his sharpness.
But as he watched the young crown prince suffer one assassination attempt after another and become surrounded by enemies, his heart softened despite himself.
"I am the sharp sword in your hand, and your unbreakable shield."
After thirteen years of sharing life and death, his feelings had burned so fiercely that he forgot the wolf cub's naturally cold heart.
One day, the birds are gone and the bow is put away. His past achievements, too, become mistakes. He grieves at the man's heartlessness and despises his own ridiculous sincerity.
In the third year after the crown prince ascends the throne, Lu Huai dies while being exiled.
He thought that the snow and wind had scattered all their grudges and passions. But when he opens his eyes again, fate has been reversed, and he has returned to ten years earlier.
This time, he holds a longbow and slowly aims an arrow at that heartless man.
He can cast aside their grudges, but he cannot let go of love and hate.
"Your Highness, it's your turn in this life."
A stoic, hidden-black-and-white, obsessive younger gong x a beautiful, strong, tragic reborn shou. Happy ending.
