The Substitute Bride Heiress Only Loves Money

I am the ghost physician's disciple. When the Eighth Prince, only eight years old, comes to the mountain for treatment in secret, he is already poisoned beyond the reach of any remedy. Drawing on my expertise as a medical doctorate in my previous life, I spend six years nursing him back to health. A handsome young man and a beautiful young woman fall in love, and I think I've got a romance about raising someone. Once he's recovered, the prince reclaims his identity. Then I overhear him telling his confidant, “How could an orphan girl like her ever be worthy of becoming my princess consort?” What an ungrateful wretch. Pay me back for the six years of medical expenses! When we meet again, it's at her empress coronation. She is the emperor's cherished favorite, while he is the crippled Seventh Prince. She never treats him again, and after her coronation, he takes his own life! But there's no medicine for regret in this world!
