### Summary
The chapter delves into the aftermath of Soohyun and Eunsung's intense sexual encounter, with Soohyun physically exhausted and emotionally conflicted. A pivotal revelation occurs as Eunsung demonstrates a detailed memory of Soohyun’s past, specifically recognizing the pen he used in high school—the same model Eunsung himself used, which Soohyun had copied. This, combined with Eunsung’s prior knowledge of Soohyun’s anxious habits and eyeglasses, confirms to Soohyun that Eunsung was acutely aware of and observant of him during their school years, completely subverting Soohyun’s long-held belief that he was invisible to his rival. This realization forces Soohyun to confront the possibility that their obsessive dynamic has always been mutual, fundamentally challenging his perception of their past and the nature of their current toxic, codependent relationship.
