The table below summarizes the key facts about Kang Sae‑byeok’s character.

Why was Sae‑byeok killed?

The marble game betrayal

• During the final round of the marble game, Sae‑byeok is caught off guard when Cho Sang‑woo pushes her off the bridge, stabbing her in the neck (Squid Game Wiki (community fan resource)).
• She dies in the hallway shortly after the glass bridge challenge.

Sang‑woo’s role

• Sang‑woo kills Sae‑byeok to eliminate a competitor and secure his own chance at the prize money (Wikipedia (online encyclopedia)).
• The act is sudden and ruthless, marking the point of no return for his character.

Impact on the plot

• Sae‑byeok’s death sets up the final confrontation between Gi‑hun and Sang‑woo.
• It also leaves Gi‑hun with the moral dilemma of whether to use the prize money to help Sae‑byeok’s remaining family.

The implication: Sae‑byeok’s murder isn’t just a plot twist — it’s the mechanism that transforms Sang‑woo from desperate colleague into irredeemable antagonist, and forces Gi‑hun to choose between vengeance and humanity.

Who is Kang Sae‑byeok?

North Korean defector background

• Sae‑byeok defected from North Korea to South Korea with her younger brother Cheol (Marie Claire (fashion and culture publication)).
• She worked as a pickpocket to survive before entering the games.

Player 067 in the games

• In the Squid Game arena, she keeps to herself but forms a quiet alliance with Gi‑hun and Ali.
• She is skilled at the honeycomb challenge and the glass bridge, but her physical ability is most visible in the marble game.

Personality and relationships

• Reserved, observant, and fiercely protective of her brother.
• Shares a subtle emotional bond with Gi‑hun, though it never fully blossoms.

What this means: Sae‑byeok’s stoicism masks deep trauma. Her backstory as a defector gives her character weight beyond the game — she represents the thousands of real people risking everything for a broken promise of a better life.

Who is Sae‑byeok in real life?

Jung Ho‑yeon’s career

• Jung Ho‑yeon made her acting debut in Squid Game — her first ever acting role (Marie Claire (fashion and culture publication)).
• She had previously worked as an international fashion model for brands like Chanel and Louis Vuitton.

Modeling before acting

• Born on June 23, 1994, she started modeling at age 16 (Wikipedia (online encyclopedia)).
• She walked runways in New York, London, and Seoul before transitioning to acting.

Awards and recognition

• Won the Screen Actors Guild Award for Outstanding Performance by a Female Actor in a Drama Series (Wikipedia (online encyclopedia)).
• Nominated for the Primetime Emmy Award for Outstanding Supporting Actress in a Drama Series (Wikipedia (online encyclopedia)).

The pattern: Jung Ho‑yeon didn’t just play Sae‑byeok; she embodied her so completely that the character and actress have become inseparable in pop culture. That identification is both a career blessing and a typecasting risk.

Will Sae‑byeok be in season 3?

Cameo possibilities

• A 2025 report suggests Sae‑byeok appears briefly as a vision in season 3, urging Gi‑hun not to kill sleeping players (Show Snob (TV commentary site)).
• The cameo lasts only a few seconds, but carries emotional weight for Gi‑hun’s moral arc.

Jung Ho‑yeon’s hints

• Jung Ho‑yeon was reportedly seen on the set of Squid Game season 3 during filming (Show Snob (TV commentary site)).
• She has not officially confirmed the appearance, but the circumstantial evidence points to a cameo.

Flashback or dream sequences

• Netflix’s Tudum article confirms the season 3 finale centers on a shocking cameo — but that cameo is Cate Blanchett’s American Recruiter, not Sae‑byeok (Netflix Tudum (official Netflix news site)).
• Sae‑byeok’s appearance would therefore be a supporting memory, not a headline twist.

The trade‑off: A Sae‑byeok cameo in season 3 would satisfy fans who mourned her, but it risks cheapening her definitive death. The show’s writers face a careful balance between nostalgia and narrative integrity.

What happens to Sae‑byeok’s brother?

Cheol after the games

• Cheol, Sae‑byeok’s younger brother, is left in the care of a nearby family after her defection.
• After Sae‑byeok’s death, the prize money she would have won likely goes to her brother through Gi‑hun’s intervention.

Potential role in season 2/3

• Teasers suggest Cheol may appear in future seasons, possibly as a character who learns about the games.
• His connection to Gi‑hun and the unresolved fate of their mother could become a subplot.

The money left by Sae‑byeok

• Gi‑hun is shown struggling with how to use the winnings; helping Cheol is an obvious choice.
• If Cheol appears, he could serve as a living reminder of Sae‑byeok’s sacrifice.

The catch: Cheol is the narrative key to Sae‑byeok’s legacy. If the show never revisits him, her death loses some of its purpose. If he does return, he’ll carry the weight of his sister’s moral debt.
