Silas became convinced that it have been an elaborate scheme that had been unfolding from the time the young woman married into his castle. If this scam came to fruition, Leila would rise to become the Demon Queen in the future. Even if it did not succeed, she would have successfully stalled his search, effectively buying time for Ellie and Andre to get married. The funny thing was that he was the only one who was kept in the dark.
The irony of it all struck him hard; here he was, the Demon King and the lord of the castle, yet he felt like the naive fool who had been blind to the deceit that was hidden behind Leila's charming facade. Each moment of reflection only deepened his sense of betrayal, and it felt as though he was the only one unaware of the truth playing out around him.
