Reborn, I Switched Betrothals with My Younger Half-Sister

In my previous life, my younger sister married Prince Qi as his principal wife, while I married a poor scholar.

Prince Qi despised her, and his concubines fought among themselves. My sister was confined to the rear courtyard and suffered terribly.

The poor scholar, however, distinguished himself, came first in the imperial examinations, and became famous throughout the land. I became the top scholar's wife and lived in splendor.

My sister stabbed me to death, and we returned together to the day we chose our marriages.

This time, she snatched the poor scholar's jade pendant first. "Sister, this time, I'll be the top scholar's wife."

But she didn't know that the poor scholar owed his success in the imperial examinations entirely to me.
