He's just an ordinary office worker who has an unusual hobby. His hobbies have never changed, writing and reading stories have even become more than just a hobby for him. "Lilian" is his pen name, although the story he wrote is unknown to many people, he continues his work until the last chapter. A secret message claiming to be a "fan of his stories" appeared anonymously on his smartphone. He didn't really care about that and responded as a normal author would respond. The sky was dark after he finished the last chapter of his story. A mysterious hole appeared suddenly while he was taking time off of work. Deja vu, as if he had experienced it and that's come out true, now the fictional world he created has merged into one with the real world! Note : I'm not an English native speaker, so please pardon me if there's an incorrect at the grammar.
