Yuriel is walking ahead of Penelope since he already knows what way to choose inside the mansion. While walking, Penelope is secretly looking around and observing their surroundings. Just like how Yuriel describes this place earlier, it is indeed gloomy and depressing to look at. The whole place is too different from the room where she was locked for several days.
It seems like her grandfather redecorated her temporary room when she was still unconscious. At least the room she was using has several items with bright colors and the wallpaper around the room somewhat brightens it a little. Maybe that trait runs through the blood of their family. They tend to care so much for one another without making it obvious to anyone.
