Billionaire's Beloved Substitute Wife with Gold Touch

My grandfather once saved the life of an elderly patriarch from a top wealthy family. When my grandfather passed away, the wealthy old man honored their agreement and arranged for me to become the fiancée of his heir, Justin.

Justin was a notorious playboy, but this engagement was my grandfather's dying wish. So, I moved into Justin's home.

Justin's sister, Nancy, was engaged to Alexander, the wealthiest man in the elite circle. However, Nancy looked down on me as her future sister-in-law at every turn.
