it all started with a twitter follow. alexa mcknight is your typical 5sos fangirl, she stalks their twitters, instagrams and is obsessed with their hilarious snapchats. she loves all four of them but has always had a special thing for calum. but deep down she knows that shes "just a fangirl" and that they will never acknowledge her existence. one night she tweets calum before going to bed, like shes been doing every night for the past 2 years of her life, knowing that he'll never see the tweet. but this time calum does see the tweet and he tweets her back. and thats when the craziness begins.All Rights Reserved
