A common plot element is the misunderstanding that leads to Erza hurting Natsu. It could be a misinterpreted action or a false piece of information. For example, in some fanfictions, a villain might manipulate the situation to make Erza think Natsu is a threat. Then, the regret part often involves Erza trying to heal Natsu if it was a physical injury, or mending their relationship if it was emotional hurt. She might isolate herself at first out of guilt before taking steps to make amends.
One plot element is the build - up to the hurting incident. There could be tension between Erza and Natsu for some time, maybe due to jealousy or differences in their approaches to things. And when Erza finally lashes out, it's a big moment. After that, the regret is shown through Erza's self - reflection. She might think back on all the good times with Natsu and how she has ruined it. So she tries to recreate those good times, like taking him to their favorite place in the guild or cooking him a special meal she used to make for him in the past to show that she wants to make things right.
One common theme is domestic bliss. They might show Natsu and Erza doing normal couple things like cooking together or decorating their home. Another theme could be facing challenges as a couple. Since they are from a magical world, these challenges could be related to magic, like protecting their family from a new magical threat.
There's also a possibility that it causes a rift in the guild. Other members might take sides. Some might side with Erza, believing she had a good reason, while others might side with Natsu, feeling that Erza was too harsh. This could create a lot of tension within the Fairy Tail guild and further complicate the relationship between Erza and Natsu.
One common theme is the 'forbidden love' aspect. Since they are comrades in the guild, some fanfictions play on the idea that their love is something they have to keep secret. Another theme is 'overcoming differences'. Natsu is impulsive while Erza is more disciplined, and fanfictions might explore how they bridge these gaps in a romantic relationship.
Adventure is a big theme. Since they are both part of Fairy Tail, they often go on quests together in fanfictions. During these adventures, their relationship deepens and turns into love. Also, the theme of protecting each other is common. They are both strong, but still show vulnerability when it comes to the other's safety.
One possible reason could be a misunderstanding. Maybe Erza misinterprets Natsu's actions as being reckless and endangering the guild, so she takes harsh measures to 'teach him a lesson'.
Another theme is growth. Fanfictions may show how Natsu and Erza grow as individuals and as a pair. For example, they could face challenges that force them to become stronger both physically and emotionally, and their relationship evolves as they overcome these obstacles.
One great fanfiction could be 'A New Adventure'. It focuses on Natsu and Erza going on a quest together that was not part of the original storyline. They face new challenges and in the process, their relationship deepens in a very platonic yet heartwarming way.
One popular fanfiction is 'Natsu and Erza's Teamwork Tales'. This story highlights their teamwork and the respect they have for each other. It's full of action and emotional moments as they face various challenges side by side. It's a great read for those who want to enjoy their relationship in a positive and appropriate way.
Well, perhaps Bokuto accidentally says something really mean to Akaashi during an intense volleyball practice. He might be frustrated with his own performance and takes it out on Akaashi. Later, he realizes how much his words have hurt Akaashi when he sees Akaashi being unusually quiet and withdrawn. So he regrets his actions deeply.
There's a fanfiction titled 'Natsu, Erza and Mira: Bonds of Friendship'. It delves deep into their relationships. It shows how Natsu's carefree nature sometimes clashes with Erza's strictness, while Mira acts as the mediator. The story also has them team up for a magic tournament, and throughout the tournament, their bond grows stronger.
