Before he left, Sasuke gave Sakura a gentle forehead poke (a huge moment), saying "I'll see you soon." It was a simple but meaningful gesture—his quiet way of showing he cared, just like how Itachi used to show his love.
Sasuke’s smile, once lost in the pain of his past, is now revived through Sakura’s presence in his life. Her presence healed him in ways nothing else could, giving him a family he thought he had lost forever. With Sakura, he found a sense of completeness.
