### Summary
Lee Soohyun's profound inferiority complex towards his high school rival, the effortlessly brilliant Jung Eunsung, has metastasized into a life-consuming obsession. For years, Soohyun, a hard-working INTJ, languished in second place, developing a twisted fixation on the charismatic and talented Eunsung (ENFP), whom he simultaneously idolized and despised. This dormant grudge was violently reawakened a decade after graduation when Soohyun derived sadistic pleasure from seeing Eunsung collapse. This event spurred him to take the drastic, self-destructive step of quitting his stable job to dedicate himself entirely to orchestrating Eunsung's downfall. His entire existence now revolves around this reckless quest for revenge against a man who was never actively malicious and, as it turns out, was completely oblivious to their supposed rivalry. The narrative's current tension peaks as Soohyun finally confronts his target, only to be met with Eunsung's failure to remember him at all. This moment has elicited overwhelming second-hand embarrassment from readers, who view Soohyun's actions as pathetic, delusional, and stalker-like. While some speculate that the perceptive Eunsung might be feigning ignorance, the consensus is that Soohyun has sacrificed his own life for a one-sided vendetta, setting the stage for a volatile and toxic dynamic driven by his unhinged psychological fixation.
