I apologize for how late this blog post is.
Anyway, "The Fan and the Flower" mainly takes place in and around an old woman's house, on the top of a hill. When this story takes place, however, is not exactly stated, though I can assume that it's when electric fans exist (20th or 21st Century?). The story is told in omniscient view, because we can hear the fan and flower's thoughts throughout their time together.
I can see two conflicts throughout the story, of which the first one was very minor; it didn't take long for the fan to win the flower's heart, apparently. The main conflict was the distance between the two and its consequences.
I think the climax happened when the fan decided that his life (?!) is a price worth paying for the survival of the flower and tore off the roof to allow rain to fall on the flower.
As for symbols, I think that the distance between the two can be interpreted as life's hardships summed up.
It could be said that the irony of the story was that even though the fan died physically, he (?) still lives on the flower, especially in the way she (?) blooms to commemorate him.
And so, I conclude that the theme of the story was that sacrifices are necessary for love.
