So Nicole is Sophie's older sister by 3 minutes. This will basically be with her in the story, she might find a love interest all the way in the end. But most of the time she will be around helping Sophie.
While Sophie has her close friends, Nicole chats alot with Sky, since he has been like a brother to her.
Sophie calls her sister Nicks
Sky calls her Nicky
And Donna just calls her Nicole, and Nicole is after the Bulgarian name that I really like, Nicolina.
Okay, so that's that. Hope you enjoy, but I will not update frequently.
