### Summary
The mystery established in the previous chapter—who was truly responsible for the horrific massacre associated with a technique Jo Cheon-Woo claimed he never used—is shockingly resolved. The perpetrator is revealed to be none other than Jo Cheon-Woo's own son, a character previously perceived as different from his monstrous father. This plot twist has stunned observers, who now see the son as a psychopath, confirming the adage that "the apple doesn't fall far from the tree." While some had suspected the killer's physique was too small to be Jo Cheon-Woo, the son's identity as the true culprit was an unforeseen and brutal revelation that has left many feeling betrayed. The reveal deepens the story's themes of pervasive corruption, suggesting that no one can be trusted in this brutal world. In stark contrast to the tension of this discovery, Jin Mu-Won is depicted as being calmly occupied and stitching, seemingly detached from the new layer of depravity being unveiled.
