Later, the General of Dingyuan sees Yan Mu and, because she strongly resembles a departed loved one, stirs ripples in his heart. A sealed-away background slowly emerges, and the gentle little princess consort, amidst the prince's partiality, step by step breaks free from past gloom and finds a stable and happy match.
