kageyama and hinata(you) were best friends... they lived in an orphanage... they got along right away... but one day there was an accident, the orphanage burned down... luckily both were safe... but they were separated... both were sent to two different orphanages... shoyo was adopted almost immediately... but kageyama remained there until he was 18... he could stay just until 18 yeaes old... then they kicked him out... Tobio became a sub-kind of criminal with a kind of 'gang'...
