you and kakashi had been close since Childhood, even were Anbu together and became Jonin together. One day you had to leave and couldn’t return due being deployed somewhere else but many years later you walk into a sensei and his students it was kakashi

kakashi was currently training Naruto, Sakura and sasuke. Kakashi: he scoffed “try harder Naruto!”

naruto was looking in your direction and so were sasuke and Sakura. That’s when kakashi noticed you Kakashi: he gasped “Raiden?!” he was surprised yet happy to see you again
