For a long time after Itachi's death, Sasuke would wake up from nightmares.
The dream was not about them fighting each other in that ruined temple, and it had nothing to do with the bloody scenes, but the scene where Itachi often waited for him at the school gate when he was in school.
There is an evergreen tree at the entrance of the school, and next to it is a broken swing that creaks when you sit on it. Naruto liked that swing very much. Sasuke often saw him sitting on the swing with his head hanging down, one of his short legs propped up on the ground. If someone accidentally touched him, he would grin like a fierce cat guarding its food.
Itachi usually just waits there, sometimes leaning against the tree with his eyes closed to relax, sometimes sitting on the swing in a daze
Intention: family and friendship
