Kidnapped by My Brothers Best Friend

Becca is sophomore in high school her mother died in a car crash and her dad was shot. Her little brother went sledding with friends and went in a coma. Becca thought she had nothing but when she goes to a 5SOS concert Luke calls her on stage she ends up telling him what happened and he ended up as her brother. Becca and Luke get in a fight one day and Becca runs out of the house. When the band goes looking for her...Harry Styles leaves a note. Will Becca ever see Luke again? Or will she be forced to live with One Direction. Btw this is my first story so it probably sucks.
