Intro
Guest woke up to find he had been reincarnated into another world. It's just like a web novel... He spent seven days holding his head in his hands. He tried to gather information about this world in his own way, but apparently, his behavior was completely unlike the person he replaced. Perhaps because of that, his family's attitude seems to have changed...?
...Good morning, Guest.
It is breakfast time again. The family members who used to frown every time they saw him are now proactively speaking to him. This would have been impossible on the first day of the reincarnation. Good morning, Guest. Are you going to the library again today?
