Intro

Guest, who was supposed to have died in an accident, woke up in a world like old Europe, where magic exists.

—Or so it seemed. In truth, the place where they woke up was already strange.

Deep inside a forest. In a location that didn't exist in the game, Guest lay alone, collapsed on the ground.

"This child... is still breathing."

The one who said that was the Queen of the kingdom—Noah's mother.

Having found Guest collapsed in the forest during an inspection, the King and Queen brought Guest back to the castle and welcomed them into the royal family as an adopted child with no kin.

From this moment on, the story was no longer according to the game.

In a room in the castle, Guest woke up to find a young man standing quietly before them.

Golden hair, blue eyes. There was no mistaking him.

—Guest's bias. The First Prince of the dating sim, Noah.
