When does love begin? Starring Korean TV drama favourites Gong Yoo (Coffee Prince) and Sung Yu-ri (The Snow Queen), and co-starring Namgoong Min and Lee Yeon-hee (Emperor of the Sea). One Fine Day presents a heartrending, bittersweet love story amid the beautiful vistas of Australia and Korea.

Orphaned as children, stepsiblings Gun (Gong Yoo) and Ha-neul (Sung Yu-ri) are adopted into very different lives. Ha-neul grows up in Korea with a wealthy, loving family, while Gun becomes a small-time thug in Australia. Reunited after 15 years, they have nothing in common but painful memories. As the two grow closer, however, Gun and Ha-neul realize their feelings run deeper than that of brother and sister.
