Betrothed to My Sister's Ex

Marie is always dressed in tatters and is treated like a servant in her own home. Then she meets Count Kyros.

Kyros hates aristocratic society and its ties of obligation. But why? And what changed when he met Marie?

Marie begins her new life as Kyros' fiancée and finds herself bewildered by the differences from her old life.

Kyros wants to provide Marie with every comfort, but Mio cautions him. Then a package from the baron arrives.

Luiphon takes Marie to a sword fighting contest. The ferocity of it scares her. Then the dark warrior fights.

Liu Liu, Kyros' mother, discovers surprising things about Marie. Mio investigates the baron on Kyros' orders.

Mio investigates a comment in a letter from Marie's brother. Marie and Kyros go to the capital for a date.

Marie and Kyros visit a renowned jeweler's in order to meet with Luiphon. Marie is astonished at the surprise that Luiphon has prepared, but she reaffirms her resolve to live as a member of the Granado family, and realizes her feelings for Kyros all over again. Then, just as Marie begins to truly enjoy the reality of her own happiness, feelings of guilt toward Anastasia begin to rise within her.

Jacob, the driver of the carriage that Anastasia was riding in on the day of the accident, is brought before Kyros. He refuses to speak, so Johan, who is from the same country as him, puts on an act in order to draw the truth out of him. The details that Jacob gives about the accident surpass anything Marie had imagined, and the deeper understanding of Anastasia they provide shakes Kyros greatly.

Could Anastasia be alive? But the person Marie suspects, Norman's apprentice, is a boy named Arthur. Worried because Marie isn't convinced by Luiphon's description, Kyros arranges for her to meet Norman. Though Norman insists that his apprentice is male, the more Marie hears about his apprentice, the stronger her suspicions grow. She slips away and disappears.

Anastasia appears and demands that Marie's betrothal to Kyros be cancelled. For some reason, Anastasia's eyes are full of loathing for Kyros, but she allows herself to be led into the castle where Marie listens to her story. She begins speaking of their past and of how she was unable to protect Marie. What was the reason for the sudden change in Marie's life, the thing that left her in tatters?

Marie is determined to settle things with the Shaderan family. With the help of Kyros and the others, she aims to force her way into the mansion where her father and mother have shut himselves away. Even in the face of the evidence, Gregor continues to resist. And with Anastasia there, it becomes clear that their mother Elvira has a secret. How will Marie confront parents like these?
