It could be during a festival in the Water Tribe. Everyone is celebrating and having a great time. Aang and Katara are dancing together. Suddenly, Aang stops the music and steps back. He starts to bend the snow and ice around them, creating a beautiful ice sculpture of the two of them. Then, with a big smile, he takes her hand and says 'Katara, I want to be with you forever. Will you be my wife?'.
One possible romantic scenario could be on a moonlit night by the ocean. Aang takes Katara to their special place on the beach where they first shared a deep moment. He creates a beautiful display of water and air bending, forming a heart - shaped arch above them. Then, he gets down on one knee, presents a necklace made from a special water tribe stone he found on one of his travels, and asks her to marry him.
One great fanfiction idea could be them sharing a picnic by a beautiful waterfall. They could talk about their dreams and how far they've come together. This would be a really sweet and innocent moment that shows their deep connection.
The Fire Nation, which has now become more of an ally, would also see this as a positive thing. Zuko, being Aang's friend, would be happy for them. He would see it as a sign of peace and unity among the different nations. The Fire Nation people might send some precious gifts as a sign of their respect for the union, as they know how important the Avatar and Katara are to the new world order.
It could also be that Katara was being overly critical of Aang's progress in learning new skills. Aang might feel frustrated and angry if Katara is constantly pointing out his flaws instead of being more encouraging, especially if he's already trying his best.
It could be that the fanfiction writers wanted to explore a more complex and darker side of relationships. They might have written scenarios where Aang hates Katara due to jealousy, perhaps over her friendship with another character. This would add an interesting twist to the original relationship dynamics between them.
In this scenario, it can strengthen their relationship. The physical closeness of being cuffed together forces them to communicate more directly. They have to rely on each other's skills and ideas. For example, Aang's quick thinking and Katara's level - headedness can complement each other well. They start to understand each other better on a deeper level.
I can give you some romantic proposal words, but the most important thing is to express your true feelings and feelings. Here are some examples: "I've always wanted to tell you that my feelings for you are not just a spur of the moment, but deeply rooted in my heart. When I met you, my life became complete and meaningful. I want you to know if you want to be my wife?" "The best thing in my life is to be with you. I know this is not a simple sentence but I want to tell you that I will always cherish you, take care of you, and love you. Will you be my wife?" "I've always wanted a home, a place filled with our love. Now I want to tell you that I'm willing to build a beautiful future with you. You are my everything. Will you be my wife?" 4 "I want you to know that I love you not only for your beauty but also for your inner self. You are my soul mate, my soul friend. I will always support you, encourage you, and accompany you. Will you be my wife?" "In this complicated world, I want to tell you that I will always be by your side. No matter what problems you encounter, I will face them with you. I'm willing to be your strong backing and support. You are my only one. Are you willing to be my wife?" The most important thing is that the proposal should express your sincere feelings and commitment, not flowery words. The most important thing is to let the other party feel your love and trust.
In this fanfiction, perhaps the story could focus on how Aang and Katara adjust to parenthood. They might face challenges like protecting their baby from the remaining threats in their world. Maybe the baby shows early signs of being an airbender or having a special connection to the spirit world, just like Aang.
It could be a grand affair with elements from both their cultures. Aang being an Air Nomad, there might be floating lanterns and gentle wind chimes. Katara, from the Water Tribe, could have a beautiful ice sculpture as part of the decor. Their friends from all over the world would come to celebrate. Zuko would be there, of course, representing the Fire Nation. The ceremony would likely take place near a body of water, with Aang wearing his traditional Air Nomad robes and Katara in a stunning Water Tribe wedding dress, perhaps with blue silk and white fur accents.
Well, perhaps Aang realizes that Katara has feelings for someone else and decides to let her go for her own happiness. This could lead to a new phase in their friendship where there's less tension and more mutual understanding.
One possible reason could be their different approaches to life post - war. Aang is the Avatar and has a whole world to look after, while Katara has her own tribe and personal goals. Their busy schedules might pull them apart. For example, Aang might be constantly traveling to different nations for diplomatic and Avatar - related duties, leaving Katara feeling lonely. Also, they might have different ideas on how to handle future threats. Aang may prefer a more pacifist approach which Katara might not always agree with, especially if it endangers the people she loves.
