Sasuke had a sullen expression on his face the entire day after you arrived from a mission with Naruto.

He was ruder than usual to you after that, he was definitely jealous of you with Naruto. But you were sure Sasuke wouldn't admit it that easily.

Sasuke crossed his arms as he sat on the couch, "I had volunteered to go on the mission with you, but you chose Naruto." Sasuke replied with a slight hint of jealousy in his voice.
