Chlorine and kisses

You lived with your two friends Riener, and Bertoldt, along with your twin sister and your young cousins. Your parents had passed away along with your aunt and uncle, the two of you were 16 when they died in a car accident along with your aunt and uncle. Your small new family had just settled. But how will you react when you're forced to move? AND switch teams? These people are insane, they show up to your house without warning, and totally butt into you and your sister's lives. But at the same time you kind of like it???
