The kiss could also strengthen their bond in the face of external threats. In the Hunger Games universe, there are always enemies. But now that they have this new level of closeness from the beach kiss, they are more determined to protect each other. They might train together more intensively or come up with new strategies to keep each other safe.
Some writers develop their relationship by exploring their individual growth within the marriage. Peeta could continue to grow as an artist, and Katniss as a protector of their home. As they support each other's dreams and goals, their relationship deepens. For instance, Peeta might paint a mural of their family, and Katniss helps him find the perfect spot for it in their house. Another way is by introducing new characters who test their relationship, like an old acquaintance from the Games who has different ideas about their future, but they get through it together.
They might have some disagreements, like how to raise the child. Katniss, who has grown up in a tough environment, might have different ideas compared to Peeta. But these differences would also help them understand each other better. They would communicate more and work through their issues together, making their relationship more solid.
In fanfiction, their beach kiss can symbolize a moment of pure connection. It might be a turning point in their relationship, away from the harshness of the Games and more into a romantic, intimate bond.
One possible scenario could be that they are finally alone after a long and arduous journey in the Hunger Games. The beach offers a peaceful and secluded place for them to express their deepening feelings. Maybe they have just overcome a major obstacle together and the kiss is a celebration of their survival and new - found closeness.
It deepens their bond. The kiss is a physical expression of their underlying feelings. It makes their relationship more intimate and shows that they are willing to be vulnerable with each other.
One way is to have them face more personal challenges together. For example, if one of them gets injured badly, the other has to take care of them and in the process, their bond deepens. Another way is to introduce a third party who is interested in one of them romantically, which makes them realize their true feelings for each other more clearly.
Gale might also experience a more complex development. He could struggle with his feelings for a long time, going back and forth between hating Peeta and Katniss for their relationship and trying to accept it. This internal struggle could shape him into a more nuanced character, with a deeper understanding of love, loss, and friendship.
In some fanfiction, it starts with animosity. Gale is jealous of Peeta's relationship with Katniss at first. But as the story progresses, they realize they all have the same goal of protecting Katniss and their district. So, they slowly start to tolerate each other and then build a friendship based on mutual respect.
The development of their love in fanfiction can be traced through their communication. In the beginning, Katniss is mostly focused on survival. But Peeta tries to communicate his feelings. He might say things that make Katniss think about him in a new way. As they go through different trials, like being tortured by the Capitol, they find comfort in each other. Their shared experiences bring them closer. And over time, their love blossoms from a hesitant acquaintance to a deep, passionate love. For instance, in some fanfictions, they might have a moment where they finally admit their true feelings after a long period of internal struggle, which is a big step in their love development.
In some fanfiction, their relationship develops quickly. They might realize their true feelings for each other right after the games end. For example, they could start a family soon and focus on building a life together away from the horror of the games.
