It is the story of a young woman who re-discovers her childhood pen pal from military service when she happens upon an epistolary exchange he sent to his dead girlfriend by a carrier pigeon.

They plan to meet in person at a train station, but Jeong-min never shows up, and thus their correspondence ends.

Later when Jeong-min reaches the age of twenty (though when this movie was shot Jun was only 17), Hyun-jun moves into her hometown.

Hyun-jun has become the owner of a pet shop for birds, and grieving over the death of his girlfriend in a car accident, he keeps sending her letters via carrier pigeon.

As she watches him care for one wounded pigeon then give an apple to a child playing nearby, she falls in love with him at first sight.
