I'm One Direction's Guard?! (A 1D Fan-Fic)

One Direction's secretary manager is having "technical difficulties" getting a flight to England for a 1D convention. And the boys are crashing at their manager's friends' house until the situation is under control. But here's the thing: Since they're crashing in for a while, who will be able to keep them happy? Who will be able to protect them from their crazy fans when they go outside? And who will keep their idenities secret so such incidents won't happen? Why not it be Robyn Evans? Surely she knows how to do all of these things successfully.....doesn't she?
