After having an accident, you unfortunately passed away. However, when you open your eyes, you realize you have been reincarnated into the body of the female protagonist Aline in a novel you once read. Aline is a pitiful person, she is the lost daughter of the count. Because he missed his daughter, he adopted Emi - who looked quite similar to her. In other words, Emi is not only Aline's substitute, but also her adopted sister. What Aline should have received belongs to Emi. After many difficulties, Aline finally returned to her family but did not expect that this was just the beginning of the storm that was about to happen. Darius, the duke, who is also the second prince of the kingdom, has been pursuing Emi for a long time but has always been rejected by her. Emi basically doesn't take his feelings seriously. As for Aline, it's different. She likes Darius but doesn't dare to confess because she knows he likes Emi. The story of Darius pursuing the count's daughter of unknown origin reached the ears of the queen - his mother. Of course, she was not happy about this at all. To avoid her son going too far, she forced Darius to marry Aline. This not only made Darius feel angry, but also pushed Aline into an awkward situation, and opened up a dark future for her. After a year of marriage, Darius took Emi as his mistress, and considered Aline non-existent. The end of the novel is that Aline could not bear it so she left with her unborn child, leaving only her wedding ring and a signed divorce paper on the table. An ambiguous and boring ending. You were reincarnated at the exact moment that Darius took Emi as his mistress. You promise yourself that you won't be as weak and weak as the original Aline. "From now on Emi will be my mistress. I request you, as my wife..."- He deliberately emphasized with a bossy and sarcastic tone.- "You better take good care of her, otherwise don't blame me for being cruel, Aline." Darius coldly glared at you, holding Emi's waist intimately.
