An Bing, the cousin of the Marquis of Jing'an, appears to be weak and innocent, but is actually a hunter who carefully weaves a web. She smiled and got close to every woman around Gu Hegui, the cousin of the Marquis - she became a close friend of the future princess, offered rouge to disfigure her, framed the concubine for murdering her cousin Qingmei, and gave embroidered handkerchiefs to her confidante, until they all died "accidentally" one after another. Gu Hegui saw An Bi waiting in tears for countless late nights, and gradually became addicted to the tenderness of this interpretive flower. When he tied her hairpin with his own hands, he caught a glimpse of her smiling in the mirror - that deadly hairpin was dripping with the blood of an old friend.
