### Summary
The central conflict escalates as Empress Dowager Medea reveals her new scheme: to arrange a marriage between Leslie and the Crown Prince, Arendo. This plan aims to secure Leslie's formidable powers and the backing of House Salvator for Medea's political ambitions. However, the relationship between Medea and the prince is highly suspect, with readers overwhelmingly concluding that she is manipulating him. Speculation centers on Arendo being addicted to a drug, possibly derived from a flower, that only Medea can provide, rendering him a dependent puppet. His strange, craving-like behavior in her presence supports this theory. Furthermore, complex fan theories have emerged regarding Arendo's parentage, suggesting Medea may have swapped him at birth with the emperor's true heir, whom she then eliminated, making Arendo her biological son. This would explain her obsessive fixation on placing him on the throne. While her accomplice Ellie remains a source of irritation, Medea's plot is seen as delusional, as it grossly underestimates the fierce opposition of the Salvator family and Leslie's own transformation into a powerful survivor who would never submit to such a union.
