    Karma Fanfic || Assassination Classroom Karma came from a rich background. As his family has always been somewhat traditional, he has no choice but to be in an arranged marriage with someone of his parents' choosing. That's when Kawasaki Asuna comes into the picture. Karma's parents have decided to choose one of their closest business partner's daughter to be their son's wife and their future daughter-in-law. Having been introduced to each other since young to bond with each other, Karma slowly became infatuated with the young, smaller, innocent girl who is to become his wife in the future. As years pass, he has never told anyone about this arrangement. He had also not been able to attend the same school as Asuna so he had obviously not expected his fiancée transferring to class 3-E one day. " Good morning, my name is Kawasaki Asuna. It's a pleasure to meet you. " *I do not own the anime and characters except for the OC and storyline. **Special thanks to @ImberLapis for making the cover! Updates every Friday!!!
