This story is purely fictitious and any similarity is purely coincidental. Although this story is sad, I think the ending is perfect because the story is just a story, not real life. Stories are not mirrors of life, but tinted glass. Every time I read this story, I want to cry. I don't know how much emotion I put into it, as if I have been with them for four years. Watching the changes of time with them, there are always too many unexpected things in relationships...
