System name: The system has zero sense of existence. After each volume of the protagonist ends, the protagonist is manipulated to make the protagonist's emotions indifferent. Although the protagonist still remembers the content of the previous volumes, the memories will only come to mind in words. Those emotions that appear with the words are similar to reading novels or watching TV. You will be moved, but only for that moment. After all, not everyone will always put themselves into the novel. This will also prevent the protagonist from collapsing due to the feelings of multiple worlds.
This article is a fan of Waiwai. If there is any similarity in content, it is purely coincidental. I just gave CP the characters in the drama that I really like.
