Marc : We Found Love by Rihanna. You and Marc were both in a tough place mentally but you have each other the strength thy you both needed to make it through.
Steven : Unconditionally by Katy Perry. Steven has loved you from the moment he first saw you and he always will love you no matter what happens.
Layla : You and I by One Direction. Layla will never let anybody or anything come between the two of you. You two went through so much together and it strengthened your bond.
Jake : Jealous by Nick Jonas (or whatever the fuck his name is now). Why? Because Jake gets jealous way to easily when he sees someone staring at you. Like the song says , You're too sexy and he doesn't want anyone looking.
