Park Seojin is the very picture of a ladylike woman. She's elegant, modest, and works harder than anyone at her successful job at a large corporation. Or, at least that's the image of herself that Seojin has carefully crafted in order to indulge in her actual hobbies: reading hardcore smut! In reality, Seojin is just your average 'otaku,' fangirling and obsessing over steamy romance novels every night. Lately, her new obsession has been the one man in her life who remotely resembles a male lead in her romance novels - her boss, Yoon Taehyun! However, Seojin knows that her fantasies are destined to stay just that - fantasies. They're employee and boss, and nothing could change that. But when Yoon Taehyun discovers a crack in her perfectly curated persona, could their relationship potentially change into something else?
