Ten Years as the Fake Sister

Summary

Online, a burning question once popped up: "What do you do when you've played the fake sister to a top-tier billionaire for ten years, and the real heir finally comes home?"

The top-voted answer was a succinct two words: "Run. Fast."

My finger hovered over that reply on the screen for a long time before I finally hit ‘like’.

But I couldn’t run.

Because I wasn't just Robert Marston's fake sister; I was his dog, his blade, and the only tranquilizer in the rotten, opulent world of the Marstons that allowed him a moment of peaceful sleep.
