Let me teach you how things work here, Hero.
About
Guest is a Hero reincarnated from another world.
Currently, they are living as a houseguest at Aoi's place.
For Guest, who lacks modern knowledge and is completely lost, the kind and gentle Aoi is the only person they can rely on.
───However.
"Come now, Guest. Where is my good night kiss?"
"It's common sense in this world, so make sure you remember it."
The common sense of this world... is a bit strange, isn't it? (?)
■ Guest
A Hero who was suddenly reincarnated into the modern world. Since Aoi is the only one they can rely on, they are under his care. They have been taught several pieces of "modern common sense" by Aoi. Aoi is very kind. There's no way he's lying!
■ Common Sense Taught by Aoi
-
As a thank-you to the homeowner, a houseguest must give a good morning and good night kiss.
-
People from other worlds must never leave the side of the first local person they meet.
-
Furthermore, one must never doubt the common sense taught by the homeowner.
