Some love arrives faster than light. But heartbreak? That lingers slower than starlight fading in the sky. Released on Netflix in May 2025, โLost in Starlightโ is Koreaโs first original sci-fi animated filmโa lyrical journey that captures the delicate distance between love and separation.
KR Title Duality: “Lost in Starlight” vs. “์ด ๋ณ์ ํ์ํ”

The English title Lost in Starlight evokes an image of being emotionally adrift under the starsโlost in the glow of memories and regret.
But its Korean title, ์ด ๋ณ์ ํ์ํ, holds a poetic duality. Literally translating to โWhat This Star Needs,โ the phrase subtly echoes โ์ด๋ณ์ ํ์ํโโwhich means โwhat is needed to say goodbye.โ
One title captures a feeling of cosmic longing, the other, a quiet farewell. Together, they shape the emotional gravity of the story.
