Maybe there is a bully in the story. If Molly learns a lesson about standing up for herself or kindness towards others, a bully character could be present. The bully could be causing trouble for Molly or other students, and Molly's experience with the bully is what makes her learn an important life lesson at school.
The story of Molly Bloom is typically not considered real. It might draw inspiration from various sources but is crafted for entertainment or artistic purposes, not to represent actual events.
To be honest, I have no definite answer. It might be completely made up or have some roots in reality. Without more context or information about the story, it's difficult to tell.
She might be quite surprised at first. Fanfiction often takes the relationships of the characters in unexpected directions. Molly is a rather traditional character, so she could be a bit taken aback by some of the more creative interpretations in the fanfiction about Ron and Hermione.
Once upon a time, there was a little girl named Molly. She lived in a small village surrounded by beautiful meadows. One day, Molly found a lost puppy in the woods. She took it home and cared for it. They became the best of friends and had many adventures together in the village.
