The fanfic could center around Wendy and Romeo's relationship development. For example, they start as friends but as they go through various challenges, they realize their feelings for each other are deeper. It could also involve other Fairy Tail members helping or hindering their relationship growth.
One great 'Wendy x Romeo' fanfic could be 'The Sky and the Flame'. It beautifully depicts their relationship as they grow older in the Fairy Tail universe. The author focuses on how Wendy's gentle nature compliments Romeo's more fiery spirit.
A good 'Wendy x Romeo' fanfic should focus on their personalities. Wendy is kind - hearted and has strong healing magic, while Romeo is ambitious. A fanfic that shows how these traits interact is great.
They could have interactions with Natsu. Natsu might give Romeo some tips on how to be a better mage, while also teasing Wendy in a friendly way. This would create a fun dynamic between the three.
Adventure is another common theme. Writers often send Wendy and Romeo on various quests together. During these adventures, their bond grows stronger. For example, they might face a powerful enemy and have to rely on each other's skills to survive.
They could start off as friends helping each other with their respective magic training. As they spend more time together, they notice little things about each other that they find endearing. For example, Romeo might notice how Wendy is always so gentle when she heals the guild's small pets, and Wendy might notice Romeo's determination when he takes on difficult quests.
One idea could be that Wendy and Romeo get caught in a magical storm that transports them to a parallel world where their powers are reversed. They have to learn to adapt and rely on each other in new ways to find their way back home.
It could be a dark wizard who is jealous of Romeo and Wendy's emerging powers. This wizard might try to steal their magic or stop them from achieving their full potential.
One common theme is growth. Both Wendy and Romeo are young characters in Fairy Tail, so a lot of fanfictions focus on their personal growth as wizards and as individuals in relation to their relationship. Another theme is friendship - turned - love. They start as friends in the guild and gradually develop deeper feelings.
One good example could be those that focus on their adventures together in the Fairy Tail guild. Maybe they go on a mission to save a small village from a dark magic threat. Another example might be a story where Romeo realizes his feelings for Wendy during a guild-wide celebration.
Maybe they accidentally get transported to a parallel world where the roles in Fairy Tail are all reversed. There, Wendy has to be the brave one leading Romeo through all the chaos to find a way back home. This could lead to a lot of character development and interesting interactions between them.
