April Kiss (2004)

Chae-won is a charming woman, who is also talented in arts. She majored in sculpture in college, and currently teaches at her private art school. One of the things that she cherishes the most is a pair of paddy birds that she received as a gift from her middle-school boyfriend. Every time Chae-won looks at the birds, she comes to recall her middle-school love. But she can't figure out if her feelings for Jeong-woo, her middle-class boyfriend, are her affection for him or simply a piece of memory. However, one thing is clear: she is currently with the guy named Kang Jae-sup. But one day, Jeong-woo shows up, and the two men find themselves embroiled in a whirlpool of love.
