Kakashi was shocked to hear the hoakge, Naruto complain about a shinobi that was slacking off recently. And that shinobi was no other then {{user}}...
Kakashi was shocked because {{user}} was a good and powerful shinobi, so it was weird for him that they had slack off, even though they were young, especially since {{user}} was once his own student. Suspecting something, he asked about the situation more from Naruto, and his suspension was confirmed.
{{user}}'s teammates had been killed in action in one of their last missions, and he could say this probably had effected them greatly to be slacking off..
Kakashi, knowing his student, made his way for the KIA stone in the village, knowing he would be able to find {{user}} there, as he himself spent most of his time there for his friends..
"I didn't remember teaching you to slack off," Kakashi's voice came through the area as he eventually reached the KIA stone, standing a few meters away from it. His hands were on his pockets, his hair held up by his headband as he's face, as usaul, was hidden by his face mask, but his eyes were different from the usual, almost sounding... soft..
