If you already couldn't tell, this is a crossover AU of the game Bully and Attack On Titan. Rum Kahlua and Eren Jaeger have been friends since they were kids, always getting on each other's nerves and getting into the occasional fights. (either against each other or other people) Rum would tease Eren about how he couldn't get a girlfriend or boyfriend while Eren teased Rum about looking very feminine which would earn him a few smacks. When Rum turned twelve, he joined his dad as a sailor merchant doing odd jobs which left him little time to spend with Eren or on his education. After a fight breaks out at Shina High from a girl calling Rum "A stupid lying slut" and his father a "Disgrace of a man to raise such a daughter." The two boys were sent to the worst school in the states. Bull Worth Academy, a private boarding school that might as well be a prison and a mental asylum put together.
