In the Middle Ages, various chivalric novels became very popular because of "The Legend of King Arthur".
In this centuries-long popularity, there has been such a story.
The romantic but extremely vulgar tradition surrounding the knight Canterbury who married the forest nymph Annevina.
Rescued the fairy Anivena from the evil lord, the two fell in love at first sight, went through hardships, and finally got married.
This vulgar story soon disappeared from history.
However, this story is only the tip of the iceberg called truth, which is obscured by fog.
