Louis Tomlinson, Harry Styles, Niall Horan, and Liam Payne are in tour Zayn Malik quit the band to become a normal 22 year old guy. It's not the same without Zayn and we all knew it wouldn't be. While the guys were performing they all broke down in tears Liam's sister Crystal turns their worst day into a good day. Crystal and Liam didn't know that they were siblings because their parents didn't want Crystal so, they put her up for adoption. What will Liam and the band do when they meet Crystal??? Will Liam take her in or not???
