It's hard to say for sure. 'One Day' could draw inspiration from real-life situations but might be heavily embellished or even completely fictionalized to make it more engaging.
Well, it's hard to say for sure. 'One Day' could be inspired by real-life incidents but have fictional elements added to make it more engaging. Or it could be completely made up from the author's imagination.
Sure. There could be. Writers are often inspired by real - life events and might be able to create a novel in a day if they are highly motivated and the story is already well - formed in their minds. It might not be a long or complex novel, but it can be based on a true story.
It's hard to say for sure. It depends on the source and the details provided. Sometimes stories are based on real events but have some fictional elements added.
