Jiang Yanyu, the fourth princess of the Zhaojing Dynasty, was born with stunning beauty, but because her life experience was a mystery, she was mistreated by the queen since she was a child and became an outcast in the palace. When she was eight years old, she accidentally learned that she was not of royal blood. From then on, she put away her innocence, used her stunning beauty as her blade and resourcefulness as her armor, and secretly plotted her way to revenge.
In the rain of begonia flowers in the Royal Garden, her dance and poems made the unhappy general prince Xie Yu'an fall in love with her. He gave up literature and took up martial arts for her and became a shield to protect the flowers; while the cold-faced and taciturn prince Fu Shiyan, although he protected her in the name of his elder brother, had already fallen in love with this nominal sister, and was tormented between ethical shackles and turbulent love. The master of all things in the world gave her power with both hands, just to win the favor of her sweetheart.
When the secret of her life is revealed, and when love and hatred intertwine, this desperate princess will finally make a choice between the prince and the general, regaining everything that belongs to her, and unlocking the ultimate love hidden under the cold face.
