### Summary
Based on the reader comments for the current chapter, a pivotal revelation occurs concerning Sangwoo's traumatic past. Readers express shock and profound pity upon learning the truth behind his parents' deaths: Sangwoo's mother, Eunseo Oh, poisoned his father and prevented Sangwoo from seeking help after his father hit his head. She then sexually assaulted Sangwoo before impaling herself on a knife he was holding, causing her own death and leaving Sangwoo burdened with misplaced guilt. This backstory humanizes Sangwoo, explaining his psychological damage and violent patterns, leading many readers to express deep sadness for his childhood trauma ("I feel bad for baby sangwoo") and disgust towards his mother ("The mum is an absolute madwoman"). While readers acknowledge this doesn't excuse Sangwoo's horrific crimes ("that doesn’t excuse all that shit he has done"), the revelation significantly shifts the emotional dynamic, fostering complex empathy ("i don't forgive sangwoo, but i get it"). The graphic nature of the revelation and its emotional weight leave readers feeling disturbed, confused, and mentally exhausted, with many explicitly mentioning a need for therapy or lighter content afterwards. The police investigation also progresses, frustrating some readers regarding prior inaction.
