Pokgunui Myeoneuriro Jeomjjikyeotseumnida

A ten-year-old girl is reborn as an insignificant citizen of an empire doomed by tyranny and famine. Using memories from her previous life, she prepares for the coming disaster by farming in a quiet village alongside neighbors who seem strangely devoted to her. But when everyone suddenly disappears, leaving only a promise to return, she is left alone—until she is kidnapped and taken to the imperial palace. There, she discovers that her friendly neighbor is actually the feared tyrant, who declares her his future daughter-in-law using a childhood scribble as a marriage contract. As the truth about her late father and hidden bloodline emerges, she realizes she may not be an ordinary extra after all.
