On finding out the nature of Tony’s business, rather than being appalled by it as most young women might, Sofia was enthralled.
Further discovering that Tony was boss, the head-honcho, and that her sister was his wife, only served to fascinate her. Sofia started to see Tony in a different light. His disinterest in her, despite being his sister-in-law, and dismissive behaviour heightened this fascination. She developed a crush on Tony, or maybe his power, which was a strong aphrodisiac. Her distance from Marcia had kept Sofia in check though.
Until now, when Marcia wanted a friend.
