The character Young-mi in 'Squid Game' always struck me as someone carrying the weight of the world on her shoulders, which made her age ambiguous at first glance. She's played by actress Lee Yoo-mi, who was in her early 20s during filming, but the character's backstory—especially her tough, survivalist demeanor—feels older than a teen. The show never explicitly states her age, but her interactions with other players suggest she's more of a young adult than a high schooler. Her role in the marble game with Ji-yeong adds layers to her personality, showing a mix of vulnerability and street-smart resilience that doesn't quite fit the typical teenage archetype. If I had to guess, I'd place her in her early 20s, though the dystopian setting makes age feel almost irrelevant compared to sheer desperation.
What's fascinating is how 'Squid Game' deliberately blurs these details—characters are defined by their choices, not demographics. Young-mi's pragmatic ruthlessness contrasts with the more naive players, reinforcing that she's weathered hardships far beyond her years. The show's costuming (like her oversized jacket) subtly hints at someone trying to appear tougher or smaller than they are, which could imply youth, but her actions scream maturity. Either way, she's one of those characters who lingers in your mind long after the credits roll.
