In the fanfiction, a significant event could be a festival or celebration in the Fairy Tail world. Lyon and Juvia might participate together, and during this time, they share some deep conversations that bring them closer.

In the process of fighting side by side, they develop a stronger bond and understanding, which ultimately leads to their relationship growing.
One possible fanfiction could involve Juvia initially being hesitant to date Lyon because of her feelings for Gray. But as she spends more time with Lyon, she discovers his own unique charm. For example, Lyon might take Juvia on a magical adventure through the Fairy Tail world, showing her places she's never seen before, which gradually makes her heart open up to him.
Their relationship could develop through shared experiences. For example, if they go on adventures together and rely on each other's magic abilities. They might start off as friends or comrades, and then slowly realize they have deeper feelings as they see the best and worst in each other during tough situations.

There could be a storyline where Juvia and Lyon are on a quest to find a rare magical item. Along the way, they encounter various obstacles like dangerous magical beasts and tricky puzzles.

Or perhaps a plot where Juvia gets injured and Lyon has to take care of her, which makes him see her in a new light.
A great plot idea could be that Lyon and Juvia are forced to go on a pretend date as part of a mission.

This shared experience could lead to a deeper bond between them.
One idea could be a story where Juvia, Lyon, and Gray have to team up to face a powerful dark wizard that is threatening the Fairy Tail guild.

In many fanfictions, Juvia's water magic and Lyon's ice magic can combine in interesting ways. For example, Juvia can create water which Lyon can then freeze into useful shapes like shields or platforms. Their combined magic could be a powerful defense against fire - based attacks.
