Driven by greed for the Liang family seal and fortune, he imprisons Yizhen’s mother in a dungeon and keeps Yizhen herself in captivity. Betrayed by another woman, Yizhen suffers a miscarriage. Pretending to yield to the Crown Prince’s demands for the family seal, she seizes the moment to rescue her mother—only to be cornered. Her mother entrusts her with the seal and sacrifices her own life so Yizhen can escape. Fleeing the palace, Yizhen vows revenge and eventually returns to Zhao Huai’an’s side, plotting a final reckoning.
