"Okay, I have a room that's spacious enough, and quite sturdy," Bianca said. Placing her hands on the sofa, she stood up.
With a nod, Bianca told their group, "Follow me."
"Okay."
One by one, the group got up from the sofa in the living room then followed Bianca to a silver-gray door with a vertical sliding system that opened right to left.
The door was unlocked. Bianca pulled the frame to the left, and soon the door opened and they could see what was behind it.
There was a tatami mat in the center; otherwise the space was pretty much empty. The moment Bianca entered, she touched the right side of the wall. Finding a switch, she pulled it.
