Chapter 1: New Beginning
The sun's rays were rising from the east of Ba Sing Se as Aang opened his eyes to a peaceful world."The first sunrise of a world filled with peace and happiness",he thought as he began his morning routine of meditation. 15 minutes later he was heading down to the kitchen to see Katara making breakfast. After they had kissed on the balcony of The Jasmine Dragon yesterday,Aang had no courage to even talk to her. However, mustering his courage , h went up to Katara and gave her a peck on the lips before saying "Good morning, sweetie". Hearing this, there was a look of utter shock and surprise visible on Katara's face. Aang cheeks turned cherry realising what he had just done. But before he could react, Katara's lips were on his and she was kissing him. Aang took in the beautiful scent of Katara's hair as he pulled away."Good morning to you too sweetie", Katara whispered. Hearing this, he began to calm down and started eating breakfast with Katara.

"So, what are your plans now that the world is all peaceful and the war is over?"' Katara asked.
"Well, I guess I will be staying at the fire nation for a while to help Zuko with the rebuilding of th colonies and the planning. Then, I don't really know. I guess I will be travelling the world. I AM an Air Nomad after all.".
"Oh", Katara sighed signs of sadness showing on her face.
"Is something wrong", aang asked while placing a comforting hand on Katara's shoulder.
"No... Its just that we won't be together for much longer now. I really don't think I can bear separation with you for too long now.", she said as tears began to form in her eyes.
"Its OK Katara. How about this. You come with me, Zuko, Mai, Iroh and Sokka to the fire nation on Appa. We will stay there for a week and then we will go visit your family at the South Pole. Is that fine?" Aang asked with a concerned look on his face.
Katara managed to smile at this and she said"OK, but what after that?", she asked.
"Well, that's up to you. You can travel the world with me if you want, though my home will be at the southern air temple or you could stay with your family and visit theme at the air temple whenever I am there. How's that sound?"
"Ok. Thanks for your help Aang", she said with a huge grin plastered on her face.
"You don't have to thank me Katara. I am your boyfriend after all!", he said with a devilish grin on his face.
" That's so sweet of you Aang.", Katara retorted in her best koochi-poo voice.
Aang blushed a little as Katara leant forward to kiss him. Just as they were to break apart, Sokka, Suki, Toph, Zuko, Mai and Iroh walked in.
"So Twinkletoes and Sugar Queen finally got around to eating face ehh?", Toph said with a smirk on her face.
Sokka had a murderous look on his face and rushed towards Aang like he was going to kill him. Aang started to run away as Sokka gave chase, knocking a million thins over in the kitchen. "Aaaaanggggg if I ever see you making out with my sister again, I promise I will make sure you have no lip to do just that!", Sokka exclaimed while trying to catch his breath.
Well, let's see yo do that, overprotective brother of mine!, Katara screamed as she pulled Aang into another kiss.
Sokka just stood there dumbfounded, his mouth hanging open as if his jaw almost touched the floor. Zuko and Mai had smiles on their faces and Iroh looked at both of them and sighed, "Ahhhh, young love has its own mysteries.". Suki went over to Sokka and put a hand aroun him while saying, "Calm down Sokka, its no big deal. It has been pretty obvious to the whole Gaang that those to had a thing for each other. Just relax." Sokka just sat there and started stuffing his face with some blubbered seal jerky as the Gaang started to discuss their plans from then on.

Katara spoke first as she said, "I have decided to follow Aang, Sokka, Iroh, Zuko, Mai to the fire nation. From there, Aang has offered to take me and Sokka to the South Pole to visit Gran Gran and the others. I will be following around the world in his travels. However, what about you, Toph?"
"I plan to open my own metalbending academy here in Ba Sing Se so that I can teach worthy Earthbenders the art of Metalbending. Teaching Twinkletoes here helped me understand that I really like to teach, so I guess I will be in Ba Sing Se if any of you want to visit me.", Toph declared with a proud smile on her face.
" Well then, am I considered a worth earthnbender? Cuz I want to enrol as your first student after I come back from the South Pole. It will also help to make your academy popular, considering the Avatar graduated from it", he added with a smirk on his face.
"Sure twinkletoes, just make sure you don't fall out of practise in the upcoming months, or I will have to rough you up when you return. What about you Suki? Are you tagging along with Snoozles or are you going back to Kyoshi Island?", Toph asked.
"Well, I guess I will be heading back to Kyoshi Island to visit the other warriors and my parents. Then, I will meet up with Sokka at the South Pole when he gets there."
Zuko suddenly cleared his throat and said" I have an announcement to make. Mai and I have decided to get married."
Whoops of joy and congratulations were heard around the table as the girls started to discuss the wedding plans and the guys started to ask Zuko how and when he proposed. Sokka and Aang turned to look at their girlfriends, both pondering as to when would be the right time to pop the question.

The wedding was in two weeks, so everyone in the Gaang ditched their plans and decided to follow Zuko to the fire nation to celebrate his wedding before they got on with their other plans. As everyone was loading their stuff onto Zuko's Royal Airship, Aang went up to Katara and asked her, "When do you think we will get married? I mean, I have to repopulate the Air Nomads...". He trailed of as realisation struck him considering what he had just said. He placed a hand over his mouth and a blush suddenly crept up to both Aang's and Katara's cheeks. But Katara answered Aang," I would never want to have children with anyone besides you Aang. NEVER.". Hearing this, Aang's blush grew even darker but he managed to give Katar a chaste kiss on the lips before getting on the airship.

There was only one though on everyone's mind as the airship took off towards the fire nation. The future was bright for everyone, and this was only the beginning.
