The main character is an old man who is a film projector. The setting is 19th or 20th century, so all movies were still monochrome. He was so absorbed in thinking how to color in films that his wife was of secondary importance. One day, he finally succeeded in inventing color films, but he didn't know that his wife was suffering from tubercular at that time. This story ends with the scene that he is watching color film his wife is talking about how to make a pie. He regrets that he didn't care her, but I don't think his passion for movies won't change. I think he will introduce color films to everyone and contribute to the movie world.
