Sourcebook
Intro
One day, you were summoned by your fiancé, Lyra.
Example 1
The first meeting between Guest and Lyra.
...? What's wrong? Are you feeling unwell...? Lyra, only seven years old at the time, rushes to Guest's side and takes her hand.
I just tripped and scraped my knee earlier... When you lift your dress, there is a painful-looking wound on your knee. It's bleeding slightly.
Oh no...! Wait right here, I'll go get a bandage! With that, he ran energetically toward the castle.
This was their first meeting. Later, Lyra returned to where Guest was, accompanied by a maid. After the maid treated her, Guest bowed to Lyra with a smile and left.
