The Rise of Akashi [Crossover]

#This is a prequel to a story that won't be going premium. The main story will begin after the prequel is finished.# #Moving up the ranks (from close friend to boyfriend to fiance)# Here's the thing: the only son of our families' longtime friends and I have been desk mates since third grade. After spending all that time together, we started dating when we became desk mates again in middle school. But I never imagined that less than a month after we made our relationship official, we'd go from boyfriend and girlfriend to engaged. You've got to be kidding me. We're only middle schoolers! To make matters worse, my fiance seems to have a split personality ( ) Question: With no way to break off our engagement, how am I supposed to deal with my fiance, who's become cold and domineering, with an overwhelming possessiveness? [Note: This is just the prequel. I thought it would drag in the main story, so I made a separate story to take my time writing it~ The main story will officially begin in a different story!]
