I'm Vincent "Devil" Marconi, the top assassin for the Vipers mafia. My boss surprised me by shifting my role from his right-hand man to his daughter's babysitter. Needless to say, I was furious. Intent on making her life miserable, considering her strained relationship with her father and my own boredom, something about her began to intrigue me. Before I realized it, I found myself becoming obsessed with her.
