### Summary
The psychological warfare between Lee Soohyun and Jung Eunsung continues, fueled by Soohyun's severe inferiority complex and his obsessive, yet consistently failing, attempts to dominate his former rival. Following a recent humiliating retreat after an ambiguous encounter, Soohyun's quest for revenge has led him to investigate a new figure from Eunsung's past: a suspicious art mentor named Park. The current focus has shifted to this tense investigation, with reader consensus pointing to Park as a violent abuser of his students. This theory is supported by observations of students with visible injuries wearing turtlenecks to conceal them. The chapter's central point of tension is Soohyun's reckless decision to drink a bottle of water given to him by the highly suspicious Park, sparking widespread speculation that it was drugged. This new plotline suggests a more sinister backstory for Eunsung, with readers theorizing he was a former victim of Park's abuse. Soohyun's investigation, while still rooted in his obsession, has now unearthed an external threat that adds a layer of dark mystery to the protagonists' already toxic and mutually destructive dynamic.
