## The Cast: Three Performances Worth Watching

**Park So Yi as Soo An** — The young actress carries the emotional weight of the film as a girl trying to make sense of years lost. Her still images alone — that quiet, searching gaze — speak volumes.

**Yuna as Jae In** — Restrained yet detailed, Yuna’s portrayal of the mysterious Jae In is heightened by stills showing the two girls lying side by side, looking at a snow globe — an image that’s equal parts tender and unsettling.

**Lim Soo Jung as Geum Ok** — Playing a mother shaken by grief and fear, Lim Soo Jung shifts from warmth when looking at her awakened daughter to cold suspicion directed at Jae In — a duality that promises to be one of the film’s most compelling threads. Notably, she also serves as the film’s producer.

This kind of layered, female-led storytelling is exactly what makes [Korean cinema](https://en.wikipedia.org/wiki/Cinema_of_South_Korea) one of the most celebrated film industries in the world right now.
