### Summary
Following the brutal assault by Satan, the narrative pivots to an unexpected moment of defiance. While still dazed, Kyungjoon instinctively strikes Satan in the face, an act that readers celebrated with a mixture of cathartic humor and applause. This confrontation is paired with significant backstory revelations, confirming theories about Kyungjoon's past life as a powerful angel named Mikael. Reader comments indicate the chapter explores a tragic romantic history between Mikael and Satan, leading to confusion and speculation about why Satan would violate his former lover. Further lore is unpacked as readers discuss the possibility that Cain and Satan were once a single entity, Lucifer, and that Mikael and Satan may have been twin brothers in their angelic past, adding a complex, quasi-incestuous layer to their relationship. The chapter thus shifts from the pure trauma of the previous installment to an act of resistance, all while dramatically expanding the mythological conflict and the intertwined histories of its central characters.
