I woke up inside a novel, and not even as an important character. I became a pretty background extra in a smut novel. My brother, however, was the only normal person in the entire story.

When she spiraled into scandals and nightlife, he was already a billionaire, calm and untouchable. I thought he would live a quiet, ascetic life forever. Until one night, I walked in on him at midnight… holding a piece of clothing I recognized all too well, murmuring a name over and over, a name so familiar that my scalp tingled.
