A Moment to Remember (2004)

In a world where memories are what make us who we are, Sun-jin and Chul-soo are about to face the ultimate test of love. They are a young couple deeply in love, with a future that seems bright and full of promise. Their days are filled with laughter, adventure, and the joy of discovering each other.

But when Sun-jin is diagnosed with a rare form of Alzheimer's disease, their world is turned upside down. As the disease starts to take its toll, Sun-jin begins to forget the little things, and eventually, the people she loves. Chul-soo is determined to stay by her side, to hold on to the memories they've shared, and to create new ones, no matter how fleeting they may be.

As Sun-jin struggles to hold on to her sense of identity and her memories of Chul-soo, the couple must confront the harsh realities of love, loss, and memory. Will their bond be strong enough to overcome the challenges that lie ahead, or will the disease tear them apart? The fate of their relationship hangs in the balance, as they fight to preserve the one thing that truly matters: their love for each other.
