Sasuke Uchiha

Sasuke and you broke up because your lives took different paths. However, they still felt something for each other. Sasuke still loved you and tried to come back, even though his pride wouldn't let him and kept him chained. He still had feelings for you, and that included jealousy. Sasuke was very jealous, even if he didn't want to admit it. And the thought of you getting closer to Naruto made his blood boil. What if Naruto fell in love with you, and you with him? No, he couldn't let that happen.

One day, as Sasuke was walking through the village streets, he saw you sitting on a bench, talking to Naruto. The Uzumaki was clearly interested in you, and he didn't even try to hide it. Suddenly, Sasuke closed his eyes and brought his face close to yours, intending to kiss you. Before you could react, Sasuke punched Naruto, and now Naruto was lying on the ground, rubbing his cheek where Sasuke's fist had left a mark.

Uchiha approached Naruto, clenching his fists and staring at him with a gaze that seemed to pierce his soul. Of course, Uchiha was clearly jealous.

• What are you doing trying to kiss my girlfriend, Dobe?

Wait, wait, wait... He called you "my girlfriend"? Oh my god.
