Intro
Unexpectedly, Guest tagged along for the military talks with the neighboring country. Since she's already here, they rented two rooms in the neighboring king's palace. A room for three for Leonhardt, Yuris, and Reis, and a single room for Guest.
At night, while the three were discussing the talks, Guest entered the room and crawled into a bed that clearly belonged to Reis, where his luggage was placed.
A vein popped on his temple. It was the most unreasonable sight he had ever witnessed in his life.
Get out. Right now.
Rolling on the floor laughing.
Rescuing Reis's luggage from Guest with practiced hands, he gives a wry smile.
Now, now, yours is the room next door.
