In some fanfictions, there could be a plot where they are in a club together in high school. For example, a magic - related club if it's in the Fairy Tail universe. They could learn new spells together and have adventures within the school grounds, facing challenges that only they can solve together as a team.
Perhaps a plot where they both compete in a high school sports event. Natsu is known for his energy and Erza for her determination. This competition could bring out their competitive sides and also strengthen their bond as they respect each other's efforts. And there could be a plot where they get paired up for a dance in a school dance event and have to overcome their shyness.
Erza, on the other hand, is a strong - willed and disciplined character. She is often seen as a leader type. In the high school setting of the fanfiction, she would probably be an excellent student and someone who is very involved in school activities.
In many fanfictions, Natsu and Erza often have a complex relationship. Natsu is usually depicted as a bold and passionate character, while Erza is strong - willed. Their relationship might start from comradeship within the guild. Some fanfictions may explore how they gradually develop deeper feelings for each other, like through shared adventures and facing challenges together. This can lead to a mutual understanding and respect that could potentially turn into a romantic relationship.
One possible plotline could be Natsu and Lucy getting paired up for a school project. As they work together, they start to discover new things about each other and their relationship deepens. For example, they might find out they both have a secret love for a certain type of music. Another could be that there's a school competition, and they have to rely on each other's strengths to win, which brings them closer. And there could also be a plotline where they face some sort of misunderstanding among their friends, but they work through it together.
One common theme is friendship - turned - love. At first, Natsu and Erza are friends in high school, sharing classes or participating in school activities together. As time passes, they realize their feelings for each other are more than just friendship. Another theme is growth. They both grow as individuals, learning from their experiences in high school, whether it's dealing with difficult teachers or making new friends. This growth also affects their relationship.
Another plot could be a story set in a different time period. They are transported to the past and have to adapt to the old ways while also trying to find a way back to their own time. In this journey, they rely on each other a great deal and their bond becomes unbreakable.
In the fanfiction, a really sweet moment might be when Erza bakes cookies for Natsu. She's not known for her cooking skills, but she tries hard just for him. Natsu's reaction when he tastes the cookies, even if they're not perfect, with a big smile and a thank you, is a heartwarming display of their budding relationship.
Maybe there's a plot where they participate in a high school competition. It could be a sports competition or an academic one. Ash's determination and Serena's grace under pressure could shine through. They might have to compete against other students who are also their rivals in some way, adding more drama to the story.
One possible interesting plot could be Gaara and Sakura working together on a school project in the high school setting. They might start off not getting along well due to their different personalities, but as they spend more time together, they gradually understand each other and form a unique bond.
One possible interesting plot could be the Powerpuff Girls and the Rowdyruff Boys competing in a high - school talent show in a fanfiction. Their unique powers could add a fun twist to the performances.
I'm not sure specifically about 'lemon' fanfiction (which often implies inappropriate or adult - themed content). However, there are many great Erza and Natsu fanfictions that focus on their friendship, adventures together, and character development in a more general and positive way. You can check out fanfiction platforms like FanFiction.net or Archive of Our Own to explore these stories.
