One Fine Day) is a 2008 road movie starring Jeon Do-yeon and Ha Jung-woo as two ex-lovers who reacquaint themselves while driving around Seoul.

[3] Lee Yoon-ki's deadpan comedy trails a pair of former lovers – he's a charismatic romantic and she's a no-nonsense realist – who bump into each other one year down the road.

Despite his nervous smiles and warm assurances (that seem slightly dodgy), you can guess from the outset that he doesn't have the ₩3.5 million (US$3,500) that he borrowed from her a year earlier.

[5] Jeon Do-yeon, as the sensible, even-tempered Hee-soo counterbalances the hysterical mother of a murdered child she played in Secret Sunshine, for which she was named best actress at Cannes in 2007.

[6][7] Ha Jung-woo, too, is winning as the compulsively charming, if unfailingly inept Byung-woon (a role also in stark opposition to his previous outing as the serial killer antagonist in Na Hong-jin's The Chaser).

In adapting the story for the screen, Lee expanded on the novella, adding to the number of people the ex-lovers encounter, and changed some details (including the ending scene).

The film translates beautifully into the Seoul urban-scape, as the narrative takes one through the city's high rises and small alleys to absorb its mellow autumnal colors.

This tension – fueled by angry resentment on Hee-soo's part and guilt on Byung-woon's – functions more or less as the film's story, in that it slowly transforms over the course of the day.
