At the top of Fransel's mansion, the office.
When the night was deep and quiet, this office still had a magic lamp burning, dispelling the darkness and illuminating the entire room.
Yuri sat alone at the desk, writing and drawing on a piece of parchment with a quill pen, seemingly still working.
Marilyn was nowhere to be seen beside Yuri; perhaps even Marilyn didn't know her young mistress was still working.
"Knock knock..."
At that moment, the office door was knocked on.
"Come in."
Yuri paused in her motion, no longer continuing her work, and instead she looked up and called out.
The office door was immediately pushed open, allowing a person to enter.
Seeing the visitor, a light smile appeared on Yuri's delicate face.
"I knew it was you."
The only person who could make Yuri reveal such a smile upon seeing them was naturally Reiger.
"I saw the light on over here and knew you weren't asleep," Reiger also smiled at Yuri and said, "How did you know it was me?"
