After Becoming a Substitute, I Bargained with the Male Lead

On the first day I transmigrated into an angst novel as its heroine, the male lead asked me to donate a kidney.

Me: "Sure. Six million, and you owe me an apology."

Male lead: "Have you lost your mind?"

Later, he got on his knees and begged me to accept his entire fortune.

Me: "Sorry, the price went up." I turned and walked toward the one man who had never made me keep score.
