The Secret Passage of the Embroidered Uniform Guard

To escape an arranged marriage, Commandery Princess Anle feigns illness and retreats to a villa, secretly investigating hard evidence of corruption among the imperial relatives. Lu Zheng, a Embroidered Uniform Guard captain, is ordered to watch her, but instead offers her a lead: "You investigate corruption, I'll investigate you." Together, they navigate one perilous step after another. Until one night, she discovers the secret imperial edict hidden at Lu Zheng's waist: kill the commandery princess. Is he friend or foe?
