It could be that the world in the light novel is too big and chaotic, and people have their own concerns and distractions. So, it's easy for them to forget about you. Also, if your character doesn't have standout qualities or actions, it's harder to be remembered.
There are many reasons why you can't remember the content of a novel the next day. The following are some of the possible reasons: The brain is still processing information during sleep: our brain can continue to process and store information while we sleep. If you read a complex novel with many characters, plots, and scenes, your brain may continue to process this information during sleep, causing the information to be forgotten or blurred when you wake up the next day. 2. The interaction between brain memory and sleep: There is an interaction between sleep and brain memory. When we are in deep sleep, the brain may trim and clean up information that is no longer important, so when we wake up the next day, some information may have been forgotten or blurred. 3. Distraction and memory: If you are too distracted when reading a novel or your attention is attracted by other things, your brain may not be able to fully concentrate, causing some information to be forgotten or blurred. 4. Reading speed and brain reaction speed: When reading a novel, the brain needs to quickly understand and process information. If you read too fast, your brain might not be able to fully understand or remember the information in the novel, resulting in the information being forgotten or blurred when you wake up the next day. In short, there could be many reasons why one could not remember the content of a novel the next day. These included the brain still processing information during sleep, the interaction between brain memory and sleep, distraction, reading speed, and brain reaction speed.
Perhaps the story is set in a chaotic or dystopian world where memories are easily lost or manipulated. Or, it could be a plot device to make the character feel isolated and drive the story forward.
It's important as it emphasizes our individuality. Each of us has a different path, and if we let others tell our story, it may be misrepresented. Our story is a part of who we are, and only we can accurately convey the essence of it, like the unique relationships we've had and how they've shaped us.
Well, it might be that the story has some sort of mind-altering element that wipes people's memory of you. Or maybe it's a test for your character to overcome this lack of recognition and make a mark.
