When they reached the room, beautiful masterpieces, artworks, and priceless items were all shattered into pieces. They saw the servants all standing by the corner shaking cowardly wondering what they should do. The girl was their superior and they can't say anything to her. Despite she isn't the owner of the house, she still holds great power for her connection with the owner.
Jo looked at what was happening and didn't know whether he should cry or laugh at what he was seeing. He was amazed at how bold the girl was and wondered how far she could go with what she was doing.
The woman was furious yet was calm about it. She too has the same feelings and thoughts as Jo. She too was curious how far she'll act like this. She did not expect her to throw a fit like a child despite her age. If she was herself back then, she would allow her for then she was lost and alone but now… things were different and she needed to be stopped.
