### Summary
The narrative centers on Lee Soohyun, a man consumed by a long-standing inferiority complex towards his former classmate, the charismatic and seemingly perfect Jung Eunsung. Throughout their school years, Soohyun’s relentless hard work only ever secured him second place behind the "effortless genius" Eunsung, fueling a twisted obsession to see him fall. After graduation, Soohyun lost all motivation, sinking into a passionless and monotonous adult life. This apathy is shattered when he witnesses a video of Eunsung collapsing during an interview. The sight of his rival's vulnerability ignites a profound sense of sadistic pleasure in Soohyun, rekindling his dormant fixation with a new, dark purpose: to watch Eunsung's complete downfall. This dynamic is foreshadowed in a flashback where Soohyun destroys his own prize-winning painting, declaring, "Because it’s mine," revealing a prideful, self-destructive, and possessive nature that now fixates entirely on Eunsung's ruin.
