It Isn't Easy Falling In Love

I read a book a couple of years ago. I don't actually remember the title or author of the book,but I do remember that the topic inspired me. So I decided to write my own story that dealt with the same scheme and concept. The story was about two people who were totally unlike but loved each other. However, there was this obstacle that prevented them from ever being together. It was a very long process and even more struggles, but the power of love lead them to each other.
