Lisanna might face a lot of backlash from the guild. Her friends could be disappointed in her and might not trust her as much. She could lose her standing in the guild and have to work hard to regain people's respect.
The consequences for Lisanna could be far - reaching. Not only would she lose Natsu's trust, but also the trust of others in the guild. She might find herself alone and isolated. Her actions could also lead to a split in the guild if some members side with Natsu and some try to defend Lisanna. This would create a lot of tension and drama in the story. In the end, she would have to take responsibility for what she did and hope to be forgiven, but it might take a very long time and a great deal of effort on her part.
She would likely feel guilty. This guilt could lead her to try and make amends with Natsu. However, it might not be easy as Natsu could be very hurt. The relationship between her and other characters in the guild could also become strained. For example, Mirajane might be disappointed in her sister. Lisanna would have to face the consequences of her actions and try to repair the damage she has caused, which could involve a long and difficult journey of self - reflection and redemption.
Well, in many fanfictions, Natsu might initially be in shock. He's a passionate character, so he could react with anger. He might lash out at Lisanna or the person she cheated with. He could also go into a state of self - doubt, wondering what he did wrong.
Lucy could face isolation. People in the fanfiction world might avoid her, and she could be left all alone. This could also lead to her losing confidence in herself as she is constantly being blamed for something she didn't do.
A plot could be that Natsu and Lisanna have been longing for a baby. They go through a magical ritual in their guild to increase their chances of having a child. Once Lisanna becomes pregnant, the whole guild gets involved. Everyone is excited and offers their help. Natsu becomes super protective of Lisanna and the unborn baby. There could be a sub - plot where an enemy tries to target Lisanna because of the powerful baby she is carrying, and Natsu has to fight to keep them safe.
Love is a very common theme. Since they have a pre - existing relationship in the original story, fanfictions often expand on their romantic feelings for each other. Another common theme is friendship. Their friendship is the foundation of their relationship, and many fanfictions explore how their friendship evolves into something more.
Another aspect could be their relationship growth within the marriage. They might have deep conversations about their past traumas and how they've overcome them. It could also show how their love has changed and become even stronger over time, with little romantic moments like stargazing together on the rooftop of their home.
In this kind of fanfiction, they might face various challenges. Maybe they'll have to find their way back on their own. They could encounter dangerous magical creatures and have to rely on their own skills and the bond between them to survive.
Well, perhaps in the fanfiction, Natsu and Lisanna discover they're having a baby unexpectedly. They then have to adjust their lives as members of Fairy Tail. Lisanna might worry about how her pregnancy will affect her ability to go on missions. Natsu, on the other hand, vows to be the best father and to keep his family safe from any threats that may come their way, be it from dark guilds or other magical creatures.
One possible plot could be that they discover the pregnancy and start preparing for the new arrival. They might face challenges like how to balance their duties in the guild with the upcoming parenthood. Natsu could be overly excited but also a bit clueless at first.
It could be a heart - warming story. The wedding might be a grand affair with all of Fairy Tail guild members present. Lisanna would look beautiful in a white dress, and Natsu, though a bit clumsy, would be full of joy. Their friends would surely pull some pranks during the wedding preparations, adding a touch of humor to the story.
One common theme is the adjustment to married life. In the world of Fairy Tail, they have their own adventures and responsibilities. So, in these fanfictions, they often have to figure out how to balance their married life with their duties as mages. Also, the theme of growth is there. They grow not just as individuals but also as a couple, learning to understand each other better and communicate more effectively in their married state.
