In fanfiction, a cute boyfriend scenario with Laxus Dreyar could be him teaching his significant other how to use lightning - based magic in a secluded area. He'd be patient yet strict. Also, consider Jellal Fernandes. A scenario for him could be that he and his partner stargaze on a quiet night on top of a hill. Jellal would share his dreams and fears, creating a very intimate moment.
One great scenario could be a date with Gray Fullbuster in the fanfiction. He might take his partner to a frozen lake he created just for them. They could skate on the ice, and Gray would be his usual cool self, but also show his softer side by making sure his partner doesn't fall. Another scenario could involve Natsu Dragneel. He'd probably take his love interest on an adventure to find a rare magical item. Along the way, they'd face challenges together and Natsu would be super protective.
Well, for Natsu, a common scenario is him getting into a friendly fight with another guild member over his partner. It's like a show of possessiveness but in a really cute and childish way. He'll puff his cheeks and declare that his partner is the best. Then there's Gray. A popular scenario for him is having a snowball fight with his girlfriend or boyfriend. It starts as a joke but ends up being a really fun and flirty time.
There can be all sorts of 'what if' scenarios. Maybe what if Natsu never joined Fairy Tail? Or what if Lucy had a different kind of magic?
Lucy could also cry when she faces betrayal. In fanfiction, there might be a new character who befriends her and then turns out to have ulterior motives. This sense of being deceived and used would be a big blow to her, and she would likely break down in tears. And sometimes, it's just the overall atmosphere of the story. If the fanfiction is set in a really dark and hopeless time in the Fairy Tail world, with the guild in danger and no clear way out, Lucy might cry out of fear and worry for her friends and the future of the guild.
Another reason could be related to his past. Maybe he has a dark secret from his past that he's afraid will be revealed. In Fairy Tail, where people are generally open and honest, the fear of being exposed and shunned because of this secret could be overwhelming. This could make him feel that the only way out is to end his life.
One way could be to have the other characters in the fanfiction show him unconditional love and support. For example, his friends in Fairy Tail could constantly remind him of his worth and the good times they've had together. They might also try to involve him in activities that he used to enjoy within the Fairy Tail world, like going on quests or participating in guild parties.
One of the funniest scenarios could be when Happy tries to 'help' Natsu cook but just ends up making a huge mess. He might accidentally add too much of an ingredient or knock over pots while flying around the kitchen in excitement.
I really like 'Fairy Tail and the Lost Fairy Tale'. In this fanfiction, the Fairy Tail guild discovers an ancient, lost fairy tale that seems to have a connection to their own powers. It has a lot of action and also delves into the backstories of some of the less - explored characters in a really interesting way. It's full of mystery and adventure.
One possible scenario is that Naruto arrives in the Fairy Tail world just as a powerful dark guild is about to destroy Fairy Tail. He uses his speed and combat skills to take on the leaders of the dark guild and defeats them. Another scenario could be that Fairy Tail is facing a magical disaster, like a powerful spell gone wrong. Naruto, with his ability to adapt quickly, figures out a way to counter the spell using his own ninja powers.
One possible scenario could be Juvia sacrificing herself to save Gray. In the heat of a battle against a powerful enemy, Juvia might use her water magic to shield Gray from a fatal attack, but at the cost of her own life. Another could be that she succumbs to a dark magic that she was trying to fight off alone, not wanting to endanger her friends. Maybe she gets caught in a cross - fire between two extremely powerful magic users and her body is too weak to withstand the impact.
One possible scenario could be Levy getting caught in a powerful dark magic spell during a battle. The spell slowly drains her life force as she tries to fight it off but fails. Another could be that she sacrifices herself to save her friends in the Fairy Tail guild. She might jump in front of a fatal attack meant for one of her beloved comrades.
