Plot

Beom-soo is a traffic control officer who aspires to become a baseball umpire. By chance he meets Hyun-joo, a theatre major who crashes her car into a tree while he is on duty. Instead of fining her, Beom-soo gives her driving lessons and they soon become friends, exchanging letters with each other when Hyun-joo returns to university. When they next meet in person Beom-soo declares his love for her, only for Hyun-joo to reject him as she plans to go overseas to study.

Three years later, Beom-soo is making his debut as a professional baseball umpire, and his feelings of love are reignited when he realises that up-and-coming actress Yoo Ha-rin is none other than Hyun-joo. The two are eventually reunited via the baseball field and resume their relationship, though Hyun-joo's affections are also pursued by Ji-min, the president of an advertising company for which she has appeared in a series of commercials. Hyun-joo eventuntually rejects Ji-min and shows up at the opening game of the Korean Series to throw the first ball, where she kisses Beom-soo in the middle of the field.
