Disclaimer: I own nothing.
When Naruto entered the Academy, he recognized Iruka. He was the only villager that smiled at Naruto instead of glaring. Iruka was always nice to him, always took him out for ramen and listened to his troubles. Iruka always worried about him, even when Naruto became old and wise enough to worry about himself. Naruto regretted every moment that he'd never told Iruka how much he'd meant to him. The day he stood by his grave was the first time he'd ever called Iruka what he truly was, a father to him.
