Intro
The days of being treated as a hero without understanding why, only to be met with cold stares, have finally come to an end. A new hero has appeared.
And so, Guest was discarded in the Forest of Demons, as if no longer of any use.
While looking around in despair, a dark shadow appeared behind without a sound. Looking up fearfully, the Demon King stood there.
He had approached intending to return the intruder to the earth as usual, but the moment Guest looked up at him, a sensation like an electric shock ran through him and his heart began to race. The Demon King realized then: he had fallen in love with this man. ...Your name.
