Well, without reading it, we can only guess. It could be that Izuku, in the context of this fanfic, has a very cute and innocent admiration for All Might similar to how a little girl would look up to her hero. Maybe it shows Izuku following All Might around, learning from him, and getting into all kinds of situations where he has to prove himself while being under All Might's wing.
In this fanfic, it may focus on Izuku's journey with the influence of All Might. Given the 'little girl' aspect, it might imply a sense of naivete and pure admiration from Izuku towards All Might. There could be parts where Izuku tries to emulate All Might in a really endearing way, like a child would. It might also explore how All Might responds to Izuku's adoration and how their relationship evolves over the course of the story.
Well, the plot could be about a young girl who idolizes Izuku. Maybe she's inspired by All Might's belief in Izuku and tries to follow in his footsteps. It could involve her training to be a hero, facing challenges like Izuku did, and learning valuable lessons along the way.
Obviously, Izuku and All Might are the main characters. Izuku is the one with the relationship to All Might described in the title, and All Might is the object of Izuku's admiration as in the 'little girl' - like admiration.
There's also a possibility that the main antagonist is another student at U.A. High School. This student could be competitive and feel threatened by the girl's relationship with Izuku. They might use underhanded tactics to try and make the girl fail or lose her confidence, adding a layer of drama and conflict to the fanfic.
One possible plot twist could be that the revelation of Izuku being All Might's son makes him a target. Villains might see him as a valuable hostage or a way to get back at All Might. Another twist could be that there are some hidden powers or abilities that Izuku inherits from All Might that were previously unknown. This could change the way he fights and his role in the hero world.
Yes, there are quite a few out there. Some explore how All Might's relationship with Izuku would change if he was his father.

In a fanfic where All Might adopts Izuku, Izuku's life would take a different turn. He'd be part of All Might's family, which means he'd be exposed to a different way of life. All Might could teach him not just about heroics but also about life values. This would shape Izuku into a more well - rounded person. Izuku would also have a stronger support system. When it comes to his quirk, All Might could help him understand and control it better. He might even be able to use All Might's influence to get better equipment for Izuku. All in all, this adoption would enhance Izuku's story in many positive ways.
