Player 003 in Squid Game is Oh Il-nam, portrayed with unsettling charisma and a deceptive air of vulnerability by veteran actor Oh Yeong-su. Initially presented as a harmless, elderly man struggling with a brain tumor, Il-nam quickly garners sympathy from Gi-hun (Player 456), who instinctively takes on a protective role. Their burgeoning friendship forms a crucial emotional anchor throughout the early games, offering a flicker of hope amidst the brutal competition.
Il-nam’s perceived weakness often works to his advantage. His trembling hands and seemingly failing memory lead other players, especially Gi-hun, to underestimate him. This allows him to navigate the games with a combination of luck and calculated reliance on others. In the first game, Red Light, Green Light, Gi-hun literally saves Il-nam from certain death, solidifying their bond and establishing Gi-hun’s unwavering loyalty.
As the games progress, Il-nam’s behavior becomes increasingly ambiguous. He displays moments of surprising competence, particularly in the sugar honeycomb challenge (Dalgona). While he feigns distress, his ability to lick the back of the honeycomb and successfully extract the shape hints at a hidden cunning. These subtle inconsistencies plant the first seeds of doubt in the viewer’s mind, suggesting there’s more to the old man than meets the eye.
The tug-of-war game further highlights Il-nam’s manipulative nature. Knowing his physical limitations, he offers a seemingly insignificant piece of advice – to lean back and take small steps – which ultimately contributes to their team’s unlikely victory. This reinforces the perception that he’s a wise, if frail, asset to the group.
The marble game serves as the ultimate test of Gi-hun’s loyalty and humanity. Il-nam intentionally feigns confusion and memory loss, forcing Gi-hun to essentially trick him out of his marbles to survive. The emotional weight of this betrayal, believing he’s caused the death of his friend, deeply impacts Gi-hun. However, viewers later learn that Il-nam intentionally allowed Gi-hun to win, sparing him from the true horror of the game. This act, though seemingly benevolent, further complicates Il-nam’s character and raises questions about his motivations.
The shocking revelation in the final episode unveils Il-nam as the mastermind behind the Squid Game, a wealthy and bored individual who orchestrated the deadly competition for his own amusement and to feel “alive” again. His terminal illness and participation in the games were all part of an elaborate charade. This revelation shatters Gi-hun’s faith in humanity and forces him to confront the horrifying reality of the system he was forced to endure.
Oh Il-nam embodies the corrupting influence of extreme wealth and the profound moral decay that can accompany it. He is a complex and unsettling character whose actions challenge the viewer’s understanding of good and evil, leaving a lasting impression long after the credits roll.
