A Costly Mistake

The world is divided among four powers, and the ambitious lords of every nation vie for supremacy, each hoping to unite the realm.

Chai Mi, the third young master of the Chai family, styled Mingyue, is carefree and uninhibited. When his heart is stirred one day, he takes up arms for Crown Prince Li Xi.

Through a twist of fate, he somehow crosses paths with Chu Yanxiu, the young tyrant of a powerful nation, and the two become hopelessly entangled.

His former friend Su Muzhi, who once loved him, turns out to be a prince of an enemy nation. He joins forces with Chai Mi’s own eldest brother and sends him plunging into the abyss of death. From then on, the crown prince’s love turns to hatred, and his nature changes completely.

After many twists and turns, Chai Mi thinks he has finally met the right person, only to be deeply hurt once more. He retreats into the common world, but when his former lover marches on his country with an army, he has no choice but to face him again, fighting back with a frail body.
