One possible plot could be that a person is walking alone at night in a forest. They come to a fork in the path. One path is well - lit by the moonlight and seems inviting, the other is dark and full of strange noises. They choose the well - lit path, which later they find out was the right choice because the dark path led to a lair of some sort of evil creature that preys on lost travelers.
Maybe the story is about a character who has to choose between two doors in an old, haunted house. They choose the one on the right. Inside the other door was a room full of ghosts ready to possess anyone who entered. But the room behind the right door had a friendly spirit that guided them out of the house safely. So they made the right choice.
You can make it more impactful by building up the suspense before the choice is made. Describe all the bad things that could happen if the wrong option is selected. Then, when the right choice is made, it feels like a huge victory. For instance, in the forest path scenario, talk about how the dark path has rumors of people disappearing and when the character chooses the right path, it's a big deal.
Perhaps Tommy stole something very precious from a powerful being. It could be a magical amulet or a special plant. In retaliation, that being used its powers to turn Tommy into a scarecrow. This way, Tommy was not only punished but also made into a scary figure to deter others from stealing.
It could be about a father having to choose between his career and family. Maybe he got a great job offer in another city but his family was well - settled where they were.
A girl was in a maze. At every junction, she had to choose right or left. She chose right at first, but it led her to a dead end. Then she went back and took the left path. It was longer but finally led her out of the maze. So, it shows that sometimes the first choice (right) might not be the right one, and the alternative (left) can bring success.
It could be that the red bump is a sign of a contagious and deadly disease that turns people into some kind of zombie - like creatures. So the story might revolve around the spread of this 'red bump' phenomenon and the fight for survival.
One plot might be that an evil sorcerer pig created a spell that made the birds forget how to use their abilities. The green bird, which was known for its boomerang - like flight, couldn't remember how to fly that way anymore. The pigs then launched a massive attack. The birds were scared and confused. But then, the youngest and smallest bird started to have visions of an ancient power that could break the spell. The birds had to follow this small bird's lead and face many scary obstacles on the way to regain their abilities and save their land.
It could be a story where 'main' is a career - driven person. She has always been focused on her work and suddenly realizes she wants a partner. So she starts looking for Mr Right. Maybe she tries online dating and meets some interesting but not - so - right guys at first.
The ending might be that the character regrets their choice. They could have chosen the easier option instead of the more challenging but potentially more rewarding one. And now they are left with a sense of what - if and longing for the alternative. For instance, if they chose to stay in a small town instead of moving to the big city for a job opportunity, they might constantly wonder about what could have been in the city.
Fear of the unknown could be a theme. When looking through a keyhole, you can't see the whole picture, and that might create a sense of unease.
One possibility is that the bus driver is a vengeful spirit. If thanked, he takes it as an insult for some unknown reason. So when a passenger thanks him, the bus suddenly enters a strange dimension, filled with fog and eerie silence.
