Here's a little Kakashi Drabble.
The war has made him look older. Even with with his silver hair, he felt older. It was a harsh time period . He's seen his team reunited and broken up again. Sasuke finally being back in the village. But many lives have been lost .
He was under constant watch and had his sights on becoming an ANBU. Working day and night. Pushing the limit. He smiled the day he saw him get off patrol and earn his mask. He wouldn't tell anyone but under that mask he cried a little. He knew Sasuke had changed for the better and he saw light and happiness. Instead of darkness that was once controlled him.
His beautiful student Sakura had grown into a fine medic. She could heal anyone. She even passed her own master in skills. Every time he saw her she was always happy dragging the rest if her team places and laughing. Under the laughs he knew she hid a dark sadness. Which she was still burying deep down inside after the war. Still she would always be the light of team 7.
He never thought he would see the day but he finally saw Naruto become Hokage. He was happy to see him follow in his Father's footsteps and his teachers ways. His boyish grin , wide on his face . Shouting how he was the greatest , forgetting the lonely days he had.
As for himself , he was growing older and found himself remembering old memories of his younger years . He himself grew into an old man . He smiled at his reflection . Still guilty of his past , happy to see his team alive. He knew he wasn't the greatest but he felt proud oh himself.
"OLD MAN!"
"Sensei"
"Kakashi-sensei!"
He hearts his team yelling for him. As he looked out the window, he could of sworn he saw his twelve year old team. He shook his head and saw three matured adults . He walked out and went to eat ramen with them, still thinking about the memories and the new ones that will arise . Even though he had his face in his book and his mask on, he still shed a tear, for the future .
Finally . I'm done with this .
