She treats “casual dress” as an excuse for sweats, ignores greetings, wears headphones at work, and threatens to quit whenever corrected. This arrogant Gen-Z employee has everyone walking on eggshells. One day, her boss visits an escort service specializing in masochistic women to relieve his stress—and recognizes the attendant as Reina Miyashita from his own office. Company policy forbids side jobs, so he exploits her secret, forces himself on her, and records it. With leverage in hand, he trains her at the office and in private through remote-vibrator play, collar sex, and submissive service. Before long, both body and mind belong to her dominant boss, who has completed her transformation into his masochistic pet.
