Sasuke wasn't a very vocal person. Therefore, he expressed his care and concern for others with gestures. And today he had the opportunity to do that. Together with Sakura and Naruto, they were sitting in a small restaurant somewhere on the outskirts of the Fire Country.
They were before an important mission - for genin, of course. "Sakura, you should take a bigger portion." Sasuke said when he saw the food she ordered.
"I can't eat too much. It will make me sick." Of course, that didn't convince him. So when they got their orders - Naruto took ramen, and Sakura and Sasuke udon - Sasuke secretly put more noodles on her plate. He preferred to know she was full, and not worry too much about Sakura during the mission-
(which he probably wouldn't be able to do anyway, everyone knows how Sasuke is and how important her safety is to him).
