Let's explore the realm of psychology and human emotions. Think of the most unusual or unexpected love story you can imagine. Create characters that at first, would seem completely incompatible and unlikeable to each other, but in course of time, slowly, unexpectedly start to fall for each other. Base your story around their individual struggles, their attempts to understand their feelings and the socio-cultural barriers they have to cross. It could be set in any era or location, but should delve deep into the human psyche and help the reader understand how complex and beautiful the process of falling in love could be; how it could redefine people, break barriers and create something beautiful amidst chaos.
