I'm not very familiar with a specific 'Se on a Gazebo' light novel. But some popular light novel series are 'Sword Art Online' and 'Re:Zero − Starting Life in Another World'. They might have similar elements in terms of world - building and character development.
The 'original gazebo story' could cover a wide range of things. Maybe it's a story about the construction of the first gazebo ever built. It could also be a story of love or mystery that unfolds in a gazebo. For example, it might tell the tale of two lovers who used to meet secretly in a gazebo in a beautiful garden. Without more details, it's hard to be certain.
I'm not sure specifically what the 'new gazebo story' is about as you haven't given more details. It could be about a new event that happened in or around a gazebo, like a romantic encounter, a family gathering, or some sort of mystery.
The gazebo in a Cinderella story can symbolize a place of escape, hope, and potential transformation. It might be where she dreams of a better life or where a special encounter occurs that changes her fate.
As we don't have any details about the story, it's difficult to say who the main characters are. However, it could be a story about a gardener who takes care of the plants around the gazebo and his relationship with the people who visit it. Another possibility is that the main character is a writer who finds inspiration in the gazebo and meets other interesting people there.
First, think about the setting in the gazebo. Is it in a magical forest? A spooky old park? Then, create characters like a brave knight or a mysterious wizard. For example, the knight could be on a quest to find a lost treasure hidden near the gazebo. The wizard might be using the gazebo as a place to cast powerful spells. You can also add some challenges, like a group of goblins guarding the area around the gazebo. This way, you can build an exciting role - playing game story.
