[Short Story] The Man Who Refused a Second Reincarnation to Another World, Received a Special Service, and Returned Normally to His Original World

As explained in the title, it's a story about the protagonist returning to modern-day Japan after saving the world. It's a narrative that touches on meta elements—the conversation with the goddess before returning, life after coming back, the reason for reincarnation, and the nature of the world. The protagonist is logical and argumentative, while the goddess is foolish.
