Rough‑mannered, illiterate female general Wei Ling seeks justice for the late Crown Prince. She pursues a marriage with Gu Mingzhu, the delicate and handsome young master of the Gu family — a costly move that comes at great risk to herself. Yet the fragile young master is nothing but a disguise. Behind the mask is Jiang Juan, the ruthless, yandere leader of the Ling Pavilion. He infiltrates the General’s Manor under Gu Mingzhu’s identity, aiming to steal the Flame Jade to cure his illness. But he never expects to lose his own heart in the process.
