In her past life, Gu Weiyu was plotted against by her eldest sister and forced to take her place in a substitute marriage, living a life of grievance and regret. Returning once more, she is no longer at the mercy of others and bravely takes back the right to choose her own life. Facing the layer upon layer of schemes within the aristocratic household, she relies on kindness, wisdom, and resilience to hold her ground, and also lets the cold-faced General Xiao Heng see her true heart and radiance. The two break through the deadlock side by side, understanding and protecting one another. The story conveys the positive power of women refusing to be manipulated and bravely choosing for themselves; true happiness is never about attachment and contention, but about finding oneself in growth, winning respect with sincerity, and rewriting life with courage.
