The Classic

The film tells the parallel love stories of a mother and daughter. The story of the mother is told partially in flashbacks.
The movie starts in the present day. The daughter, Ji-hye (Son Ye-jin), is cleaning-up around her house when she comes across a box full of old letters and a diary that detail the story of her mother, Joo-hee (who is also played by Son Ye-jin). Periodically in the movie, Ji-hye reads one of these letters, which starts a flashback scene in which the story of the mother is told. These flashbacks are intertwined with Ji-hye's own story, in which she falls for a fellow student, Sang-min (Jo In-sung), who is involved with the school theater.
The movie tells the story of both relationships. The mother, Joo-hee, visits the countryside as a student one summer and meets Joon-ha (Jo Seung-woo). Together they explore the countryside, playing near a river which they both will always remember as their special place. When a storm starts they take shelter together under a tree, but not before Joo-hee twists her ankle and is rendered helpless. Joon-ha carries her on his back and they struggle home, only to be confronted by her angry parents. Before they separate, Joo-hee gives him a necklace, which he keeps close as a precious reminder of their time together.
Unfortunately, as often happens in affairs of the heart, a third party prevents any deepening of their relationship. Joo-hee has been promised by her parents as a bride to Tae-soo, Joon-ha's friend. But Tae-soo, a noble friend, finds out about Joo-hee and Joon-ha's attraction for each other and helps the two communicate secretly by letting them use his own name in place of Joon-ha's in their letters. When Tae-soo's father finds this out, however, he beats Tae-soo. Tae-soo tries unsuccessfully to commit suicide so that his two friends can be together.
Meanwhile, in the present, Ji-hye falls for Sang-min in whom her friend Soo-kyeong is also very interested, but he seems not to notice. Then, in a sweet scene, they take shelter from the rain together under the same tree. He uses his coat to cover both of them and escorts her to where she needs to go. The moment, while magical, does not go anywhere as she feels his help was only due to his generous nature and not from any feelings for her on his part.
Back in the past, Joon-ha is guilt-ridden over his friend's attempted suicide and Joo-hee's own guilt. Determined to prevent any more hurt to her, Joon-ha joins the army and goes to Vietnam. There he loses his eyesight while he tries to retrieve the necklace Joo-hee had given him. When he returns to Korea, he meets again with Joo-hee, and, trying to hide his blindness, convinces her he has married in the hope she will move on with her life. Though heart broken that their relationship cannot continue, she does move on and eventually marries Tae-soo, Joon-ha's kind friend. After they have been married for several years and have a young daughter (Ji-hye) Joo-hee is approached by friends of Joon-ha, who relate Joon-ha's last wish: that his ashes be scattered by Joo-hee in the river, now a reservoir, where they first met. She then finds out that Joon-ha hadn't married, but he later did after Tae-soo and Joo-hee were married. She was told that he had a son also. The heart-break is too much and she cries.
In the present, Ji-hye's own story unfolds. Sang-min reveals his true feelings for Ji-hyeÂ â feelings that mirror her own. It is also revealed that their taking shelter together during the storm was no accident: he had purposely left his umbrella behind in a shop so that he could join her under the tree. Then, when Ji-hye pensively reveals her mother's story to him, tears stream down his face. Silently he lifts a necklace from around his neck and places it around hers. It is the necklace that Ji-hye's mother, Joo-hee, had given to Joon-ha when they met. The circle is completed: Joo-hee's daughter and Joon-ha's son have fallen in love.
