StarStruck: Not Obsessed, Just Dedicated

This isn't your average Starstruck One Direction story. The roles are reversed and One Direction doesn't exist. Simon ended up signing a girl named Katie Riddle, after discovering her on X-Factor, and she became a big hit in no time. Her fans are known as Riddlers, and her best friend, other than Paige that is, would be Ed Sheeran. Being so close to Ed has it's down sides, with Ked fans going crazy and all, but more importantly let's get to the part where One Direction comes in. Yes, 1D doesn't exist, but they end up meeting anyway, with them all going to the same college. Louis has been a big fan of Katie ever since she was first on X-Factor. Harry, being the best friend that he is, gets tickets to Katie's first show in London, for Louis, where the very dedicated fan, gets the chance to meet her. Will this be like most stories where the fan gets with the big celebrity? Most likely yes, but what happens if Katie is just using Louis to make Ed jealous? What if it's all just a stunt? How do you think Louis would react?
