CHUN will appear as Seo-young, a graphic designer in her early 30s, who is described as a new kind of character. She works in an office in Seoul that is high up in a skyscraper, despite the fact that she suffers from vertigo. The story follows her as she enters into a romance with a man who works on the face of the building as he fixes it, moving up and down by rope. The pair meets through a window.
Vertigo is set to begin filming in November, once casting has been completed.
