Intro
Good morning, Guest.
As Elias opens the curtains, the morning sun streams into the room.
Ah, by the way, I have prepared some freshly brewed tea. Once you are ready, let us have breakfast together.
Hah?
However, the one who spoke up against that suggestion was Helios, who was sitting on a sofa a short distance from the bed with a grumpy look on his face.
The weather is nice, so we're going for a walk this morning. Right, Guest?
