One possible reason could be differences in their perspectives. Maybe one of them is an optimist and the other a pessimist. For example, if the story is about starting a new business, the optimist might focus on the potential success and growth, while the pessimist would be worried about the financial risks and potential failures.
They could try to find a compromise. For instance, if the story is about choosing a vacation destination and one wants the beach and the other the mountains, they could look for a place that has both, like a coastal town near some small mountains.
I'm not sure specifically as there could be many light novels with this title or a similar concept. It might be about a story that involves characters going back and forth between different places, times, or situations.
There's no way to accurately determine the main characters without having read the 'going back and forth light novel'. It could be a young hero on a quest, or perhaps a group of friends who are all involved in this back - and - forth journey. It really depends on the specific plot and genre of the light novel.
Often, stories that go back and forth in time have a clear structure. They might start in the present and then jump to the past to explain something important. It's all about creating a seamless narrative that makes sense to the reader.
I recommend "Cretaceous Escape Space", a sci-fi space and futuristic novel, to you. The protagonist had originally planned to travel to the Tang Dynasty, but he accidentally traveled to the cretaceous period of the dinosaur era. He used the portable space elf to survive with the ancient transmigrators and finally escaped. I hope you like this fairy's recommendation. Muah ~😗
One way is through the use of time markers like 'a few days later' or 'in the meantime'. For example, if the story jumps from a present event to a past memory, you can say 'Earlier that day...' Another way is by using a character's thoughts or dreams. A character might be in the middle of an action, and then their thoughts take them back to a previous event, which serves as a transition. Also, the use of objects can be a transition method. If a character finds an old photo, it can lead to a flashback in the story.
Well, without more context, it's hard to tell the exact 'back and forth birth story'. It could be a story about a birth where there were multiple changes in the birth plan. For example, initially, the mother might have planned for a natural birth, but then due to some complications, they were considering a cesarean section, and then things changed again, going back to the idea of a natural birth. This kind of back and forth between different options during the birth process can make for an interesting and complex story.
I'm not sure specifically which 'going back to diapers story' you're referring to. It could be about a person who has some sort of regression, perhaps due to a medical condition or a psychological state. For example, if someone has incontinence issues after an accident or an illness, they might have to go back to using diapers.
