The Dayan Dynasty was peaceful on the surface, but undercurrents were turbulent. The lively and kind-hearted eldest princess Liang Ruoxi deeply loves her two younger brothers with very different personalities. The second prince, Liang Jingyuan, looks calm and elegant on the surface, focusing on calligraphy and painting, but in fact he has a strategic mind and secretly accumulates strength; the third prince, Liang Jingrui, seems to be free and unrestrained, wandering around the world, but in fact he is very scheming and good at calculations. As the emperor became ill from overwork and gradually moved away from the center of power, the two princes' covetousness for the throne gradually surfaced, and the overt and covert struggles became increasingly fierce. Ruoxi is involved in this, trying to maintain the fragile relationship between siblings and trying to resolve the deepening estrangement and suspicion. However, behind the surface of tenderness, the shadow of intrigue always hangs. In this unavoidable whirlpool of power, what kind of cruel test will the love between loved ones face?
