Caitlin and Lex are just two 16 year old twin sisters who've always been there for each other, just like best friends. Lex has a boyfriend, but things don't always go too well in their relationship. And Caitlin recently got out of a relationship where everything seemed to be perfect, but in reality it was terrible. Everything was normal and fine in their lives as it was, but what happens when 5SOS moves in next door in their LA house for a while? This could totally change things. P.S. This ones for all the Michael and Luke girls out there(;
