Player number: 067 ·

Six key facts about Kang Sae‑byeok, drawn from official sources and the show’s wiki:

Is Player 067 a girl or boy?

Character identity and gender

Player 067 is unequivocally female. The character’s full name is Kang Sae‑byeok, and she is always referred to with feminine pronouns in English and Korean versions of the show. According to Wikipedia (community-edited encyclopedia), she is “a North Korean defector who enters the Squid Game to win money for her family.”

Actress portrayal

The role is played by South Korean model and actress HoYeon Jung, her first acting job (Seventeen (pop culture magazine)). Creator Hwang Dong‑hyuk said he cast Jung because she had “the gaze of a wild horse,” as Wikipedia records.

The implication: Player 067’s gender is never ambiguous in canon, but the character’s androgynous style and survivalist intensity often surprise new viewers who assume a male player.

Is Sae‑byeok actually from North Korea?

North Korean defector background

Yes. Sae‑byeok and her family defected from North Korea. According to Wikipedia, her father died during the escape, her mother was caught and presumably returned to the North, and her younger brother Cheol was placed in an orphanage. Sae‑byeok entered the games to win enough money to take Cheol to safety and potentially rescue her mother.

Family story

The Squid Game Wiki (fan wiki) adds that she later worked independently after a falling out with gangster Jang Deok‑su, creating the animosity that surfaces during the games. Her brother Cheol is played by child actor Cho Yoo‑jang, though the character has few lines.

Meaning of the name Sae Byeok

In Korean, “Sae‑byeok” ( ) means “dawn” (Wikipedia). The name is weighted with symbolism: dawn follows darkness, a hint of hope for a character whose story ends in tragic darkness.

Who is the actress that played Sae Byeok?

HoYeon Jung’s career

Jung Ho‑yeon (known internationally as HoYeon Jung) is a South Korean model who skyrocketed to fame after Squid Game. Before acting, she was a top runway model for brands like Chanel and Louis Vuitton. Squid Game was her debut acting role, as noted by Seventeen.

Awards and recognition

Jung’s performance earned her the Screen Actors Guild Award for Outstanding Performance by a Female Actor in a Drama Series (IMDb). She also received a Primetime Emmy Award nomination for Outstanding Supporting Actress in a Drama Series (IMDb). According to the Netflix Queue page, Jung was nervous because it was her first major role, and she prepared by watching documentaries about North Korean defectors and keeping an in‑character journal (KIRO7 Seattle (local news)).

The pattern: a model with zero screen credits delivers a breakout performance, wins top industry awards, and becomes one of Netflix’s most recognizable stars—all from a single role.

Why was Sae‑byeok killed?

Circumstances of death

In episode 8, after completing the glass bridge game, Sae‑byeok and Gi‑hun reach the final dormitory. She is stabbed by fellow player Cho Sang‑woo while Gi‑hun is distracted. According to Wikipedia, Sang‑woo kills her to prevent Gi‑hun and her from voting to end the games and split the prize money. The death is sudden, unglamorous—she was one step away from the final face‑off.

Role of Front Man

The Front Man (Player 001, played by Oh Young‑soo) oversees the games but does not personally kill Sae‑byeok. Some fan discussions misattribute the death to him; the show clearly assigns it to Sang‑woo. The motive is pure survival: Sang‑woo believes eliminating Sae‑byeok gives him better odds.

Aftermath

Gi‑hun carries her body to the final game, and in the emotional finale, he tracks down her brother Cheol and leaves money with a guardian in her memory. The Netflix YouTube channel (official streamer) frames her as having “fire and fierceness that is no match for the Squid Games”—a fitting epitaph for a character who burned out right before the finish line.

What’s the saddest death in the Squid Game?

Comparison of notable deaths

Squid Game kills off nearly every supporting character, but fans consistently rank Sae‑byeok’s death as the most heartbreaking. A comparison of the leading contenders:

Four candidates, one pattern: each death carries a unique emotional weight, but Sae‑byeok’s backstory gives hers extra depth.

Why Sae‑byeok’s death is considered saddest

According to Seventeen and fan polls, her death is often cited as the saddest because of everything she had already lost: her father, her homeland, her mother, and then, seconds before freedom, her own life. David Opie of Digital Spy, quoted in Wikipedia, described it as “hard‑hitting.” The shot of her brother waiting with a teddy bear, unaware, amplifies the grief.

Other contenders

Ji‑yeong’s sacrifice is arguably more noble, and Ali’s betrayal is more shocking. But Sae‑byeok’s arc—from desperate defector to tough survivor to dead body on a dormitory floor—carries the weight of the show’s critique of economic inequality. The trade‑off: while Ji‑yeong died by choice, Sae‑byeok died by someone else’s calculation, which feels crueler.

“I researched the role by watching documentaries about North Korean defectors and writing a journal in character.”

“Sae‑byeok has fire and fierceness that is no match for the Squid Games.”

— Netflix official short (Netflix YouTube (official streamer))

The trade‑off for Sae‑byeok is that her survival skills—honed by a life on the run—make her one of the strongest players, yet they cannot protect her from the betrayal she never saw coming. For fans, the sadness is not just that she dies, but that she was so close to the life she had been fighting for since childhood.
