They could start by having common goals. For instance, if the guild is in danger, they both contribute in their own ways and start to respect each other's abilities more. This mutual respect can be the foundation for a deeper relationship.
Another way is to put them in a situation where they have to rely on each other completely. Maybe they are trapped in a magical dimension where only their combined magic can get them out. During their time trapped, they open up about their fears and dreams. Elfman might talk about his dream to be as strong as his sister, and Evergreen could talk about her dream to be truly accepted in the guild. This sharing and relying on each other would strengthen their relationship.
In a fanfiction, a good way to develop their relationship is through character growth. Let's say Evergreen decides to train Elfman in some aspects of magic control. As she teaches him, she sees his determination and hard work, and he sees her patience and intelligence. This interaction can gradually turn into a romantic connection as they spend more time together and learn more about each other.
Elfman's development could involve him becoming more confident in his non - physical abilities. With Evergreen's influence, he could explore his magical side more deeply. He might start to study different types of magic that Evergreen introduces him to. Evergreen could be developed to be more empathetic. As she gets closer to Elfman, she realizes that his simple view of the world has its own charm. She could start to be more involved in the guild's more physical activities, like helping with building repairs, which she would never have considered before.
One way to explore their relationship in a pregnant fanfiction is to look at how they support each other. Elfman could be the physical strength, helping Evergreen with tasks that become difficult during pregnancy. Evergreen, on the other hand, could be the emotional support, calming Elfman's fears about being a father. They might also have to deal with insecurities, like Elfman worrying if he'll be a good enough father since he has his own past traumas, and Evergreen wondering if she can balance motherhood with her role in the guild. This exploration of their insecurities and how they overcome them together can be a great way to delve into their relationship.
One idea could be that Elfman and Evergreen are sent on a mission together alone. They start off bickering as usual, but as they face various challenges, they begin to understand each other better. For example, they have to work together to defeat a powerful dark mage. During this time, Elfman discovers Evergreen's insecurities behind her tough exterior, and Evergreen realizes that Elfman is not just a brute but has a kind heart.
A possible plotline is a love triangle. Maybe another character has feelings for Evergreen and Elfman has to compete for her affection. This could create a lot of drama and tension in the fanfiction. For instance, the other character could be constantly trying to undermine Elfman in Evergreen's eyes.
In some fanfictions, they could participate in a guild - wide competition. While competing, they form an alliance and start to communicate more. They find out that they have a lot in common, like their love for the guild and their desire to become stronger. This shared ground could be the basis for their relationship to develop in the story.
One possible plot could be that Elfman and Evergreen are assigned on a mission together in the Fairy Tail guild. At first, they bicker as they have different approaches. Elfman is more about brute strength and Evergreen is more tactical. But as the mission progresses, they start to see the value in each other's methods. They face a powerful dark mage, and in the heat of the battle, they realize their feelings for each other, leading to a new relationship within the guild.
The relationship can be developed through shared experiences. For example, if they are both involved in rescuing a kidnapped guild member. They'll face danger together, and Freed might use his magic to protect Lucy from harm, which will make Lucy see him in a new light. This will create a sense of trust between them.
They could have flashbacks during the wedding planning of all the times they've saved each other. This would deepen their connection and show how far they've come. For example, when Natsu saved Lucy from the Phantom Lord attack.
Their relationship can be developed through shared adventures. For example, when they go on a quest together, they start to rely on each other more. This builds trust and makes them closer.
Their relationship can be developed through shared battles. For example, in a tough fight against a strong guild from another town, they rely on each other. Natsu protects Erza when she's in a vulnerable state during a requip, and Erza in turn uses her strategic mind to guide Natsu's brute force attacks. This mutual dependence can strengthen their bond.
