Kidnapped, By One Direction?!

Ciara was living in a downtown apartment with her younger sister Suzaine and her mother. While her mother is at work all day, Ciara looks after Suzaine. It was just a day like any other- but there was a noise. And a guy. Oh, wait, no, another guy. And another. And another. And another. What are they doing there, who are they, and why did they take Ciara and Suzaine?
