# WebtoonLib — Double Trap #4

## Series
- title: Double Trap
- slug: double-trap-13ca70

## Chapter
- number: 4
- release_date: 2025-03-09

### Summary
The narrative has pivoted sharply towards psychological horror, a shift cemented by a single, profoundly disturbing panel that has unified reader reactions in fear and shock. The core conflict remains Jinsung's emotional turmoil, amplified by a painful interaction where Yura reinforces their "family" boundary, a moment of heartbreak that resonated deeply with the audience. This rejection is widely interpreted as further evidence for the dominant fan theory: Yura has Dissociative Identity Disorder (DID), with his cold "day" persona repressing romantic feelings that are then violently acted upon by his lustful nocturnal alter. The chapter's defining feature, however, is a terrifying, "creepy" grin from Yura, which readers have overwhelmingly labeled a "jumpscare." This unsettling expression has triggered numerous and alarming comparisons to the infamous antagonist Sangwoo from \*Killing Stalking\*, solidifying the story's horror elements and leaving readers genuinely scared for Jinsung's safety. While the DID theory holds firm, the focus has shifted from the psychological drama to the palpable sense of dread surrounding Yura's fractured and menacing psyche.
