Sae Byeok – Full Character Profile, Actress and Death

Kang Sae‑byeok, better known as Player 067, is one of the most memorable characters from the global phenomenon Squid Game. A North Korean defector with a tragic past, she enters the deadly competition with one goal: reunite her family. Portrayed by South Korean model‑turned‑actor HoYeon Jung (Jung Ho‑yeon), Sae‑byeok quickly became a fan favourite for her resilience, quiet strength, and heartbreaking arc. This article brings together everything known about the character, the actress who brought her to life, and the unanswered questions that still linger.

In the series, Sae‑byeok’s backstory is revealed gradually. She fled North Korea with her parents and younger brother, but the escape ended in tragedy.

Which actress played Sae‑byeok?

Kang Sae‑byeok is portrayed by HoYeon Jung (Jung Ho‑yeon), a South Korean model and actress born on June 23, 1994. Before Squid Game, she was best known for her work on the runway, having walked for high‑fashion brands such as Chanel, Louis Vuitton, and Fendi. Her transition to acting earned her widespread acclaim and a Screen Actors Guild Award for Outstanding Performance by a Female Actor in a Drama Series.

Preparing for the role

According to the Wikipedia entry for Kang Sae‑byeok, Jung Ho‑yeon researched North Korean defectors and wrote a journal in character to authentically portray the trauma and guardedness of her role. That preparation shows in every scene, from the cold stare she gives other players to the quiet desperation when she talks about her brother.

How did Sae‑byeok die in Squid Game?

Sae‑byeok’s death is one of the most shocking moments in the series. After surviving the marble game in Episode 6, she is seriously injured by broken glass during the night before the glass bridge challenge. Bleeding heavily and unable to continue, she lies in the dormitory while a vote to stop the games is called. Cho Sang‑woo (Player 218) approaches her under the pretence of comfort, then slits her throat to prevent a majority vote that could free the remaining players. The scene is described in detail on the Squid Game Wiki.

The marble game aftermath

Earlier that day, Sae‑byeok partnered with Ji‑yeong (Player 240) in the marble game. After a tense round of deception, Ji‑yeong deliberately lost, sacrificing herself so Sae‑byeok could continue. That win came at an emotional cost, and Sae‑byeok’s eventual death soon after underscores the show’s critique of capitalist brutality.

What does “Sae‑byeok” mean?

The name “Sae‑byeok” (새벽) is a Korean word that translates to “dawn” or “daybreak”. This meaning is an interpretation based on the Korean language itself, rather than an in‑universe explanation given in the show. Fans and critics have noted the symbolism: Sae‑byeok represents hope and the possibility of a new beginning, even as she moves through a world of despair. Her character arc, from desperate defector to someone willing to trust a teammate, mirrors the gradual light of dawn breaking through darkness.

How old is Sae‑byeok?

The series never states Kang Sae‑byeok’s exact age. Viewers know she is a young adult, likely in her mid‑to‑late twenties, but no definitive number is provided. The actress, HoYeon Jung, was born in 1994 and was approximately 27 years old when filming Squid Game. As of June 2026, she is 31. That contrast between the actress’s known age and the character’s unspecified age fuels ongoing discussion among fans.

The defection story

Sae‑byeok’s family history is central to her motivation. She defected from North Korea with her parents and younger brother Cheol. During the crossing, her father died.

After that, Cheol was placed in a shelter or orphanage, and Sae‑byeok entered the games to earn enough money to bring her mother to South Korea and rescue her brother.
