In his past life in modern-day Japan, Kenzaburou Tondabayashi was a 52-year-old civil servant—now, he's the villainess! Reborn as Grace Auvergne, the drill-haired antagonist from an otome game his daughter once played, Kenzaburou is utterly bewildered.
Armed with only a handful of memories, Kenzaburou knows he’s supposed to embody the role of a haughty noble girl, but the disciplined, older man can’t quite pull it off. Instead, his natural calm and kindness make him an unexpected ally to the heroine and quickly earn him the admiration of his peers as the epitome of grace and sophistication.
As he tries to steer the story back on course, Kenzaburou must rely on his years of experience in the workforce, impeccable manners, and family-oriented values to navigate his new life and fit in with the youthful crowd.
