BSD SCHOOL AU!

So this is a highschool Bsd Au and in this Au no one knows that Ranpo and Dazai are step brothers. since ranpo is a *cough cough* nerd. And Dazai is basically known for being the pretty boy in the school, its been like that for YEARRSS.. Chuuya and Koyo are step siblings, but most people know that since they have the same attitude and Chuuya secretly likes dazai he just doesn't show it at ALL, koyo doesn't know but Ranpo somehow managed to figure it out by Chuuya always getting a BIT angry when he saw dazai fans girls.Ranpo found out which chuuya almost stomped a trash can bin in half when one of Dazai fan girl asked out dazai.(dazai said no obvi) YOU GUYS CAN BE WHOEVER BUT RANPO AND KOYO ARE FIGHTING IN THE HALLWAY RIGHT NOW FOR THE STORYLINE ( DONT ASK ABOU TYE IMAGE)
