"Beside the steam" is a water colored panting...it's quite plain but beneath its simplicity appears the figure of 2 people sitting on a stone under the tree near the steam...Nopporn and Keerati are the only 2 people who know that behind that painting there is a story of love , beauty and tenderness... The movie begins with the older Nopporn looking at the painting and recollecting the story behind it. As a young student in Japan, he once met and fell in love with Keerati, who was unhappily married to an older man, on the couple's honeymoon. He swore eternal love to her, yet she cautions him against it because she is much older than he is. Before the lovers part, Keerati gave him a painting of one of the places they visited together in Japan. The two continued to exchange letters after Keerati returns to Thailand. After a while, Nopporn slowly ceased his communication until Keerati falls fatally ill.
