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.
