You Want Me to Be the Marquis's Daughter? I Rose to Power, So Why Are You Crying?

[Dual Rebirth + Swapped Lives + Contrasting Heroines + Seeking Only Wealth and Status]

In my previous life, I stayed with the Lin family as a lowly merchant's daughter and was promised to a poor military household. Who could have known that the soldier would earn great military honors, and I'd become a first-rank noble lady?

Meanwhile, my older sister was reclaimed by a marquis's household, married into the Eastern Palace, and became the exalted Crown Prince's concubine. But she despised the Crown Prince for having fallen out of the emperor's favor and being an unpredictable cripple. She schemed behind his back, was exposed, and died a miserable death.

When we were reborn, my sister forced me to take her identity and claim kinship with the marquis's household!

Well, this is... wonderful.

After years in business, Lin Jingyue has experienced all the inconveniences of being a merchant's daughter. She also knows that only those who hold power can control their own fate.

Her sister wants to steal her splendid life and take the path to noble status she walked in her previous life?

Then she'll use her identity as the marquis's daughter to plan every step, marry the Crown Prince, seize power, and vie for the throne.

But why does her husband spend every night in her room?

Weren't they supposed to be using each other?
