My Younger Half-Sister Broke Off the Engagement, So I Married the Crown Prince and Ruled the World

In her previous life, Nangong Yan, the illegitimate daughter of the Marquis of Zhenbei's household, was greedy and took the marriage that belonged to her legitimate elder sister, Nangong Yu, and the Crown Prince. She married the Crown Prince in splendor, while Nangong Yu married the Ninth Prince.

But Nangong Yan used every means at her disposal in the Crown Prince's residence and still met a miserable end. She eventually died a wretched death.

Her elder sister, Nangong Yu, lived peacefully in the prince's residence through her own wisdom and kindness, and ultimately became empress.

In this life, the sisters are both reborn.

Nangong Yan, convinced she knows what is coming, threatens to die, defies her parents, and would rather die than marry the Crown Prince. She insists on marrying the Ninth Prince instead. What she doesn't know is that the Ninth Prince's rise to power in their previous life had another explanation.

Nangong Yu sees through her sister's scheme but says nothing, and goes along with the arrangement to marry the Crown Prince. From a young age, she has known that a woman must be independent and strong. When a woman is strong, she can defy fate in any situation. Besides, the Crown Prince is the one destined to rule.

After their marriage, Nangong Yu proceeds with caution and plans every move. In the end, she wins the Crown Prince's genuine affection and helps him ascend the throne as the new emperor. She is named empress. When the new emperor dies, the court is thrown into turmoil. She steps out from behind the scenes and becomes empress in her own right.

Meanwhile, her younger half-sister Nangong Yan dies in prison on the night of the new empress's enthronement ceremony, still unable to accept her fate.
