Three words.
Three stupid meaningless words that went to far into that.
They stood infront of each other, both on the verge of tears, but one already crying.
"I hate you." They stood there, looking each other strait in the eye.
"I don't ever want you to see nor talk to me, Toph, or Sokka anymore."
They fight just starting out with bending then came to more and more server terms. He knew her mother was a touchy subject and she knew that the dead air benders was a touchy subject.
"As you wish." he said before turning around and running away, tears streaming down his face falling on the cold forest floor. That was their first fight as a couple and probably their last fight as a couple.
The girl turned away and headed back to camp. When she got their she saw Sokka and Toph around the camp fire, Toph leaning on Sokka, as they laughed and talked. Katara groaned and ran right past Sokka and Toph and strait into her tent.
The next day Aang finally came back from his misery. For the next few weeks things have been quiet between the two. One slept at camp while the other one, after dinner, said he would go meditate but stay there all night.
Aang and Katara sat on opposite sides of the campfire, while eating dinner, breakfast, lunch, etc...But, they couldn't stop staring at each other with hate in their eyes.
Aang probably was on the verge of going into the avatar state and never coming out after seeing Katara flirt with another guy when they landed into a city to get supplies and food.
Later that week, they left the city and went back into a forest. But that night would change the life of the two lovers, well...use to be lovers.
