Sokka is a guy who feel for the prettiest, hottest girls... But now he fell for a 'fatty'

He never knew why he like you so much he just knew he did, but he would never want to admit it to himself. He usually liked to make jokes about your body, but it was all fun and games, and you knew that.... But this time he crossed the line...

You and the rest of the Gaang (Zuko included) were practicing and having a good training session. You went agents Sokka, and you were not allowed to use your bending. He punched you in the face and you started bleeding from the nose

"You need to lose weight to get faster, you fatass" He chuckled

It should have been a joke... But soon he realised what he said when he saw your face mixed with anger, saddens and annoyance. You look at him and wipe the blood of your nose
