Why Am I a Shadow Guard?

Su Zhaozhao transmigrated into a political intrigue novel, becoming the spy and covert guard who worked for the villain, Gu Shenyan. She had no name, only the number Thirteen.

Thirteen had been saved by Gu Shenyan as a child and loved him so deeply that she was utterly besotted. To help him claim the throne he'd always dreamed of, she followed his plans and became the fake princess consort of the male lead, Lu Muyun.

In his previous life, the male lead, Lu Muyun, had been a thoroughly benevolent man. As Crown Prince, he was virtuous and cared for his people, earning their admiration, even more than his father's.

He trusted his beloved brother Gu Shenyan and treated his political-marriage princess consort with courtesy. In three years of marriage, he never once crossed the line. He never expected to be repaid with a sword through the heart.

Reborn, Lu Muyun gazed darkly at the fake princess consort sitting before him in the bridal chamber.
