Under the arrangement of this system, he kept traveling through the world of various stories, from romance to science fiction, from fantasy to the apocalypse. When he experienced various different lives, there was something in his memory that did not belong to him. It was a person he had no impression of but liked very much.
Purpose: I don't want to grow up, either mentally or physically.
