Tale of a caged bird||Naruto fan fiction

"What?!" I yelled in disbelief. Old man Hokage couln't be that cruel now, could he?
"You heared me and my decision is final." he looked at me, an apologetic glint in his dark eyes, framed by age-spots and wrinkles.
"Yes, Hokage-sama." bowing my head I left the room.
"Stupid old man." I cursed under my breath, making my way, to meet my new teammates.
My name is Nezumi Hyuuga and life sucks.
