One idea could be that Levy discovers she's pregnant during a big guild mission. This could add a whole new layer of tension as Gajeel becomes overly protective. Maybe they have to face an enemy who specifically targets Levy because of her pregnancy. Another plot could involve Levy struggling with the changes in her body and magic while pregnant, and Gajeel having to learn how to support her in ways he never thought possible.
Well, perhaps there could be a plot where Levy has a difficult pregnancy. Gajeel is constantly worried and tries to seek help from different sources. They could visit a powerful mage who gives them a prophecy about their child's future. This prophecy could be both a blessing and a curse, leading them to make certain decisions to ensure a positive future for their family. And along the way, their relationship deepens as they face these challenges together.
A possible plot could be that Gajeel and Levy go on a journey to find a special place to raise their child. Along the way, they encounter old enemies who now see the pregnant Levy as an easy target. But they fight together, with Gajeel being extra protective. Also, they could have different ideas about parenting. Levy might want a more studious and peaceful upbringing for the baby, while Gajeel wants to train the baby to be tough from a young age. They then have to find a middle ground.
A plot idea could be that their family goes on a journey to find a long - lost magical tome that Levy has always dreamed of reading. Along the way, they face various challenges like bandits and magical traps. Gajeel uses his combat skills to fend off threats, and Levy uses her knowledge to solve the puzzles.
Well, here's another plot. Levy starts training with a very skilled mage who is known for his gentle teaching methods. Gajeel is jealous because he feels like he should be the one teaching Levy. So, he challenges the other mage to a friendly duel. Levy is angry at Gajeel at first for being so possessive, but later she understands that it's his way of showing his care for her. During the duel, Gajeel realizes that the other mage is not a threat to his relationship with Levy and they all become friends in the end.
Perhaps there's a fanfiction where Levy is praised for her intelligence in front of the whole guild by an elder mage. Gajeel, feeling a bit inferior in that aspect, gets jealous. He starts to study more magic theory secretly to impress Levy. Along the way, there are cute moments where he tries to ask Levy for help without admitting his real motive, and it all builds up to a heartwarming moment between them.
Perhaps a fanfiction where Gajeel is cursed with a blue mark that slowly drains his energy. Levy, being the studious mage she is, devotes all her time to finding a cure. Along the way, they have to face many enemies who are after Gajeel's power. Their love and friendship are put to the test as they struggle to break the curse.
One interesting plot could be their honeymoon adventures. Maybe they go to a magical island where they encounter new magical creatures that Levy has only read about in books. They could have to use Gajeel's strength and Levy's intelligence to overcome the challenges there.
One interesting story could be where Gajeel and Levy are adjusting to life with a new baby. The baby might inherit Gajeel's tough exterior but also Levy's intelligence. For example, in the fanfic, the baby shows an early aptitude for magic, which surprises everyone in the Fairy Tail guild. It could also explore how they handle the challenges of parenting while still being part of the guild and going on missions.
Their relationship would likely become more protective. Gajeel would be constantly on guard to keep Levy and the unborn baby safe. He'd be more gentle and caring towards her.
One interesting plot idea could be that Gajeel discovers a new type of dragon magic that only Levy can help him understand. Maybe it's a magic that involves ancient dragon runes, and Levy's knowledge of books and languages is crucial in deciphering it. As they explore this new magic together, their relationship deepens.
A possible plot could be that Levy's sickness is a side - effect of overusing her magic while trying to save the guild from a great danger. Her fellow Fairy Tail members take turns to take care of her and in the process, they all learn more about the importance of balance in using magic.
