Fanfiction.net is also a good place. There are numerous fanfics on different pairings, including 'vanessa x mike'. Just use the search bar and type in the relevant keywords. However, the interface might be a bit more basic compared to AO3.
One popular 'vanessa x mike fanfic' could be 'The Unlikely Bond'. It focuses on how Vanessa and Mike, who are from different backgrounds in the story's universe, gradually come to understand and support each other. Their relationship develops through various challenges they face together.
Communication is key. They can start by sharing their fears and hopes. For instance, Gregory can talk about his loneliness before coming to this place, and Vanessa can share her own struggles with her job. This mutual understanding will bring them closer.
The setting also plays a huge role in such fanfiction. If it's set in the same universe as the original source material, there could be elements of horror and mystery that seep into their relationship. For example, they might be trying to solve a mystery together while also dealing with their growing feelings for each other. This can add an extra layer of tension and excitement to the story.
The relationship can start with suspicion. Gregory is a strange kid in the pizzeria and Vanessa is an employee. But as they face danger together, like running from the animatronics, they start to trust each other more. For example, Gregory might save Vanessa from a sudden attack by one of the animatronics, and that could be a turning point.
One common theme is friendship. Since they are characters in the same universe, many fanfics explore how they become friends and support each other. For example, in some stories, Gregory might be in a difficult situation and Vanessa comes to his aid, and from there a strong friendship develops.
Since we don't have much information, Vanessa could be anyone. She might be a character in a book, a real - life person known to a specific group, or just a name created for the story.
One common theme is trust. Since they are often in a dangerous and strange situation in the FNAF world, they have to learn to trust each other. For example, in many fanfictions, Gregory has to trust Vanessa's knowledge of the place to escape safely.
Some specific fandom - dedicated forums might also have Gregory x Vanessa fanfiction. These forums are often a great place to find more niche or unique stories that might not be as easily found on the larger fanfiction platforms. You can engage with other fans in these forums and ask for recommendations as well.
