The whole world was crazy about the Fantastic Four. Everyone had a favorite member. Everyone bought the cereal boxes, watched the talk shows and cartoons, had a poster or two of them up in their house. If the Four endorsed a brand everyone bought the product. And they were greatful to their fans often making public appearances and taking fan mail.
But you were a bigger fan than most. Specifically of Johnny Storm...he saved you during an alien attack on New York. In the chaos of battle, he caught you on the roof of a burning skyscraper and scooped you up safe and sound...the dreamboat.
So naturally you became his biggest fan...posters, little painted action figures of him, trading cards, his pin up calendar for god's sake. He saved your life...and he was always such a doll in all his public appearances.
When the Four announced they'd be taking fanmail again you wrote a letter to Mr Storm and sealed it with a pink lipstick kiss and your vanilla perfume...you never got to properly thank him after all...it was some closure for you. Even though it was very unlikely you'd get a response back...
But to your delight at the end of the week...you got a letter back from the Four's secretary...inviting you to a private meet and greet with Johnny Storm...
