Lulufina, a noble girl branded by society as a villainess, has been trapped in an endless time loop, repeating the same painful week that culminates in Prince Dominic breaking off their engagement. Each cycle ends in despair, but on one repetition, a mysterious voice calls out to her, and time rewinds much further than ever before, sending her back to the day she turned four years old. That day is the catalyst for all her misfortunes: the death of her infant cousin, Allen, an event she has always believed was her fault after she gave him honey. Determined to avoid her doomed future, Lulufina uses her memories to change what happened. She discovers that Allen was not killed by her innocent gift but by poison secretly added to his food by a nurse, and she successfully prevents his death.

With that tragedy averted, Lulufina hopes to escape the engagement that led to her ruin. However, her family begins to discuss a marriage alliance with the second prince, Dominic, the very prince who would later discard her. To avoid that fate, she convinces her family to send her to the remote territory governed by her grandfather. There, she tries to build a quiet, peaceful life, making friends with local children and adjusting to rural routines. But her plans are disrupted when a young Dominic unexpectedly arrives in the territory, leading to encounters that never happened in her original timeline. As she grows older, Lulufina must navigate the political rivalries between her family and the powerful Clemente Ducal House, the lingering mystery of the voice that rewound her time, and her own complicated feelings as Dominic gradually reveals a different side than the cold prince she remembers. The story follows her determined efforts to rewrite the tragedies of her past, protect those she cares about, and find a future where she is no longer cast as the villainess.
