It could be a young adult who has just graduated from college and is starting their first job, so they are beginning a new path. The 'lemon' could be their quirky roommate who makes their new living situation interesting.
The main character could also be a new character introduced into the fanfic's universe. For instance, in a Lord of the Rings - style fanfic, a young elf who has grown up in a secluded part of the forest. One day, they decide to leave their home and start a new path, which leads them to get involved in the larger events of the war against Sauron, perhaps by forming an alliance with humans and dwarves.
Perhaps the fanfic is set in a post - apocalyptic world where the main character has to begin a new path of survival. The 'lemon' aspect could be a strange or difficult relationship they form with another survivor. They might have different goals and values at first, causing friction, but as they journey together, they start to understand and rely on each other more.
There could be a group of rogue Death Eaters who escaped justice and have banded together again. They believe that Voldemort's ideas were right but that he was too weak. So they target Harry, thinking that if they can defeat him, they can finally achieve their goal of a pure - blood - dominated wizarding world. They might be more cunning and less flashy than Voldemort, making them a more difficult enemy to detect.
Since I don't know the specific 'a new path fanfic', I can't tell who the main characters are. They could be original characters created for the fanfic or existing characters from the source material it's based on.
There could be a new professor at Hogwarts. Maybe a young and brilliant wizard who has just returned from a long journey in a far - away magical land. This professor could bring in new ideas and spells, and become an important figure in Harry's new path.
One possible plot idea could be that the main character in the fanfic decides to leave their old, mundane life behind. For example, if it's a fanfic based on a fantasy world, they might leave their small village to become an adventurer in a big city. They could face challenges like making new friends, learning new skills, and dealing with the politics of the adventuring guilds.
It could be a young, idealistic protagonist who is not satisfied with the current options for the future and decides to pioneer the third path. Maybe someone with a special gift or ability that gives them the confidence to take on this challenge.
Maybe a group of rebels who are tired of the two existing power structures in their world. They could band together and through their combined efforts and different perspectives, find the third path to the future. Each of them could bring something unique to the table, like one being good at technology, another at persuasion, and so on.
Well, of course, the babysitter would be one of the main characters. She could be a young girl, maybe in her late teens or early twenties, who is trying to earn some extra money while also dealing with her own personal issues.
In a 'lemon animal fanfic', the main characters might be a family of lemon - colored bunnies. The mother bunny is very protective, the father bunny is brave and goes out to find food, and the baby bunnies are curious and always getting into trouble. They live in a burrow at the edge of a meadow and interact with other animals like birds and squirrels.
