Abused in her family home and isolated even after marriage, a duchess is ultimately used by the emperor’s nephew, falsely branded a villainess, and sentenced to death by fire. Just before everything ends, she desperately wishes for a second chance—and somehow returns to the past, determined to take revenge. But when she reunites with her husband, he is nothing like before. Instead of being distant, he has become strangely overprotective and is even studying how to treat his wife properly. As her plans for revenge are thrown off by his awkward but sincere affection, her second life begins to take an unexpected turn.
