Zayn and Perrie were never supposed to be inside that train. It is impressive how someone’s life can turn upside down just after an encounter like the one they had. Zayn is a boy from the Southside who is humble, loving and quiet, who lives with his parents and loves spending time with his best friend Leigh, while she has to find ways to balance work and life at home with her sister diagnosed with depression. Perrie is a girl from the Northside who can be spoiled, yet respectful and open minded, who lives with her parents, older brother and younger sister. She is best friends with her ex boyfriend Niall, who is rich and sort of a douche bag, who takes an interest in Leigh. Zayn and Perrie will face ups and downs in their relationship, whilst their best friends deal with an even more complicated relationship fighting all the odds to be together.
