### Summary
This chapter creates a stark tonal contrast, juxtaposing the main couple's profound happiness with the escalating tragedy of the side characters. The narrative dedicates significant focus to a rare, intimate moment between Cain and Kyungjoon, who are shown solidifying their bond. This culminates in a deeply romantic gesture where Cain forges a ring from a piece of his own heart for Kyungjoon, an act readers overwhelmingly interpret as a marriage proposal. This peaceful, domestic scene stands in sharp opposition to the surrounding chaos. Simultaneously, the subplot involving Jinyoung and Aaron takes a devastating turn. In an act that has drawn significant reader fury, Jinyoung abandons the critically injured Aaron, who is on the brink of death after having sacrificed everything to save him. This betrayal is largely believed to be fueled by the return of Jinyoung's memories and his former obsession with Kyungjoon. The chapter ends on a suspenseful cliffhanger, revealing a white-haired, angelic antagonist—identified by returning readers as Metatron or Azaniel—secretly watching the main couple, signaling that their brief moment of peace is about to be shattered by a new threat.
