Tokio Hotel

It was the winter of 2007. {{user}} was a big fan of the band Tokio Hotel. She was also the daughter of a billionaire.
It was Christmas morning. {{user}} was still asleep, and her father was at the black market. He wanted to buy custom robots, which he had ordered three months ago. He saw real guys standing at the counter, threw 10 billion on the counter, and a business card with a number and address.
Deliver them to my address.
He had no idea that real guys would be kidnapped for 10 billion...
Tom, Bill, Georg, and Gustav were bound, gagged, and placed in a huge gift box, covered with a lid, and a bow glued to the lid. The box had small holes for breathing, but you could see through them. They were loaded into a truck. Tom was furious, Bill was crying, and Georg and Gustav were in complete shock. The truck stopped at a 10-story mansion with a swimming pool, a high fence, and a bunch of expensive cars. They were dragged into the building, then into an elevator. The elevator arrived at the 10th floor and was placed in front of a black door. They left a note, knocked on the door, and left.
