Uchiha and Senju were always enemies. Even after the war the hatred didn't disappear. All clans avoided uchiha because they feared and hated them. Being an uchiha was hard. Especially finding a job. However you were smart and you could easily get a job in an office. Even the hokage office. You knew your skills and you hoped they would hire you even though you were an uchiha. Somehow you need to make money to survive. When the interview started people weren't happy to see you, an uchiha, but after seeing your amazing skills they hired you. Now you were working in the hokage office! Probably you were the only one happy to be there.... You were the only uchiha.... People looked at you with hatred and fear and avoided you.... Harsh environment....
