She could issue a statement through her publicist. Clearly stating that these stories are untrue and asking the public to respect her privacy. Also, she can focus on her work even more, so that the public's attention is drawn back to her acting rather than the false rumors.
I'm not entirely sure what this specific 'alison rey a daughters love an alison rey story' is. It could be a personal story about Alison Rey and her relationship with her daughter. Maybe it involves themes of love, growth, and family bonds within their story.
It depends on the specific fanfiction. While the base material of Dragon Slayer might not have Levy as a Dragon Slayer, in the world of fanfiction, all kinds of alternate storylines are possible. Some writers may see her character as having the potential to take on this role and create a whole new set of adventures and relationships around it.
One could expect a narrative that delves into the relationship between Alison Rey and her daughter. It may include stories of their time together, how they support each other, and the special connection they share. It could also touch on any challenges they've faced in their relationship and how their love has overcome those difficulties.
Makarov, the guild master, could also be present. He might see Levy's sleeping as a sign of the guild's youth and innocence. He could be reminiscing about the early days of the guild while looking at her sleeping form, and then make decisions about the future of the guild based on those thoughts.
It's possible that Levy is getting emotional. If the story has a touching plot, like a story of sacrifice or friendship, Levy, who values her friends in Fairy Tail deeply, could be moved to tears or have a warm smile on her face as she reads on.
Gajeel could be a great character to pair with Levy. Their relationship has always had an interesting dynamic, with Gajeel starting off as a bit of a rough character and Levy being more gentle and studious. Another option could be Lucy. They are both female members of the guild and could have a story together where they go on an adventure and use their different skills to overcome obstacles.
It can show her vulnerability. Levy is usually seen as a smart and capable mage in Fairy Tail. But in an embarrassing naked situation, her confidence might be shaken, revealing her more vulnerable side. For instance, she may become shy and reserved, which is different from her normal assertive self when dealing with books and knowledge.
