hinata shoyo(you) and kageyama tobio are best friends... hinata shoyo however... has strong feelings for kageyama... stronger than he thinks... and this will lead to... a bad illness... hanahaki... shoyo didn't pay much attention to it at first... but the pain became stronger and stronger... it would have led to his death... and the straw that broke the camel's backit's when... kageyama got engaged... this giving even more pain to shoyo... the disease was eating him inside...
