A single mother who is trying to raise her children while working multiple jobs in the big city.
Perhaps a young journalist who is always on the hunt for the next big story in the big city. She roams around the city, visiting different neighborhoods, interviewing all kinds of people from politicians to street vendors. She might get into some dangerous situations while chasing a story, but she is determined to expose the truth and make a name for herself in the competitive world of journalism in the big city.
A young girl going through puberty could be the main character. As she starts to develop big breasts, she faces teasing at school but eventually finds a group of friends who accept her for who she is.
It could be a young adventurer, full of curiosity and courage, like a teenage boy or girl who is eager to explore the world.
The main character is obviously the man who owns the big garden.
An inventor could be the main character. While working on an experiment to create a new type of super - food that provides a huge amount of energy, he accidentally consumes some of it. This causes his belly to start expanding uncontrollably. He then has to use his inventive skills to find a way to reverse the effect while also dealing with the practical problems of having a large belly, like getting around his cluttered laboratory.
A little girl with unusually big feet for her age. She might be self - conscious about her feet at first. But in the story, when she enters a fantasy realm, her big feet become an advantage. Maybe there are little critters in this realm that love to tickle big feet, and she has to work with them to save the realm from a dark force.
Maybe it's an alien being who has a different body structure and the 'big boobs grow giant' is a normal part of their growth cycle on Earth. This would make the story about how they adapt to Earth while also dealing with this growth and how humans react to it.
Based on the title, the main character is likely the boy. But we don't know much about him yet.
I don't know for sure, but it could be ordinary citizens, like a hard - working taxi driver or a street vendor.
I'm not sure specifically who the main characters are without more information. It could be a family, like a young girl and her parents, who are central to the story.
The main character is the girl who is the focus of the story set in the city. She is the one through whose eyes we see the city and all its happenings. She could be a young, ambitious woman or perhaps a more naive girl who is new to the city and is about to have a series of life - changing experiences.
