Eh? Heibon desu yo??

For Yukari, the life of an ordinary high school student came to a shattering halt beneath the wheels of a reckless driver. But fate, it seemed, had other plans—granting her a second act as the daughter of a count in a world of medieval fantasy. Yet the glamorous noble existence she anticipated crumbles the moment she opens her eyes to her new reality. The grand manor is a dilapidated shell, the family coffers are frighteningly empty, and her prestigious title does little to mask the gnawing hunger and mounting debts that define her days. Far from a life of leisure, Yukari awakens to find herself trapped in a crushing cycle of poverty, where every corner of her inherited estate screams of neglect and ruin. Refusing to let her second chance wither away in destitution, Yukari resolves to leverage the most unexpected asset at her disposal: the accumulated knowledge from her previous life as a modern-day student. Armed with practical memories of basic chemistry, household economics, and everyday innovations, she quietly begins to rebuild her family's fortunes from the ground up. From creating simple yet profitable goods to introducing efficient techniques that breathe new life into the count's meager lands, her unassuming interventions slowly start to yield results. But in a society that prizes lineage and tradition above all, every small success draws wary eyes. To save her household and secure her future, Yukari must carefully apply her modern wisdom while keeping her extraordinary origins hidden—proving that even the most ordinary knowledge can become an extraordinary weapon when wielded by a determined soul.
