### Summary
The narrative has reached a devastating emotional climax with the shocking and violent betrayal of the demon Cain by his most trusted subordinate, Sid. This act of treachery is portrayed as particularly cruel, as Cain, caught completely off-guard by the attack, apparently offered no resistance, highlighting the depth of his misplaced trust. The reader response is overwhelmingly one of furious outrage and heartbreak, with comments expressing visceral hatred for Sid and demanding a violent, painful retribution for his actions. This event has left the central couple in crisis; Cain is grievously wounded, and his human partner, Kyungjoon, is shown to be emotionally shattered, eliciting deep sympathy from the audience. While a few readers speculate about a potential tragic backstory to explain Sid’s motivations, the dominant sentiment is that his betrayal is an unforgivable act of ingratitude that has destroyed millennia of loyalty. The chapter solidifies Sid as the ultimate antagonist, leaving the protagonists in a state of extreme vulnerability and emotional turmoil.
