This story follows Grelan, who moved to the town of Al at the age of ten and met Shyima, a girl around his age. The two grew up together in this fairy-tale town, gradually falling for each other and eventually falling in love. Just as they were preparing to marry, war broke out in their country. After Grelan went to the front, he was buried alive in a bombardment, abused after being captured, and forced to fight a bear in a prisoner-of-war camp. In the end, he lost his memory and was taken in by a group of refugees from another country.
Meanwhile, Shyima waited anxiously after Grelan went to war. Even when the war ended, he was still missing. Yet Shyima continued to believe that Grelan was alive, since the casualty report listed him as missing. As she searched for Grelan, she also pursued their shared dream of writing a book. Through her efforts, her novel, Don't Forget, featuring herself and Grelan as its characters, was successfully published and later translated into several languages and released in countries around the world. After diplomatic relations were restored with the countries they had once fought, her book was published there as well. One day, Grelan, now a beggar with no memory, happened to see it. Will he regain his memories? Will he return to his country and reunite with Shyima and his family...?
