## Chapter

### Summary
This chapter's flashback definitively reveals Sangwoo's mother, Eunseo Oh, as the primary architect of his trauma and the family's destruction. Readers react with shock and condemnation as Eunseo is exposed poisoning Sangwoo's father (confirming she, not Sangwoo, was the killer) and attempting to slowly poison young Sangwoo himself. This explains Sangwoo's earlier immunity to Bum's rat poison attempt. Eunseo's actions – including forcing Sangwoo to witness her infidelity – are universally interpreted as the core source of his severe psychological damage, warping his understanding of relationships and violence. The narrative draws explicit parallels between Eunseo's abuse of Sangwoo (offering an apple before poisoning) and Sangwoo's later treatment of Bum. While some express sympathy for Sangwoo's horrific childhood suffering, the chapter unambiguously portrays Eunseo as the catalyst for the family's tragedy and Sangwoo's descent into psychopathy.
