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.
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.
One scenario could be that the boyfriend makes her homemade soup. He carefully prepares it with fresh ingredients, just like her mom used to make when she was sick as a child. Then he brings it to her in bed, with a warm smile and a gentle touch on her forehead to check her fever.
Well, sometimes in such a fanfic, the couple could be watching a movie. The girlfriend makes a sassy comment about the movie, and the boyfriend tickles her in response. She wriggles around on the couch, and they have a mini tickle fight that turns into a make - out session as the movie continues to play in the background.
One common scenario could be that the wife feels more emotionally connected to her boyfriend. Maybe her husband is always busy with work and neglects her emotional needs. So, she gravitates towards the boyfriend who gives her more attention and makes her feel special.
One way Naruto might absorb chakra in fanfiction is if he has some sort of curse mark that instead of being a hindrance, it gives him the power to absorb chakra. He could touch an enemy with the curse mark and drain their chakra. Also, in some fanfictions, Naruto might be able to absorb chakra due to a new training regime. He could train with a hermit who teaches him a special meditation technique that allows him to draw in chakra from all around him.
One possible scenario is that Naruto travels to a hidden village that specializes in sword - based ninjutsu. There, he learns their techniques and gains the ability to conjure swords. Another could be that he is cursed by an evil ninja, but as a side - effect of the curse, he can now conjure swords. He then has to learn to control this new power.
One scenario might be related to a failed mission. Maybe Naruto is sent on a top - secret mission that is much more dangerous than anyone anticipated. He could be betrayed by someone he trusts during the mission, leading to his death. Or perhaps there are some unforeseen circumstances, like a strange and deadly curse that gets unleashed during the mission which he succumbs to.
One scenario could be that Gaara secretly follows Naruto on his missions. He wants to make sure Naruto is safe and also wants to learn from how Naruto approaches different challenges during the missions. Another could be that Gaara starts to collect little things that remind him of Naruto, like a headband similar to Naruto's or a small charm that Naruto once gave to someone else.
Perhaps Naruto gets transported into a virtual reality game world where he has to team up with other virtual characters, some of whom are based on his real - life friends and enemies. They then embark on a grand adventure to save the game world from a digital apocalypse.
