Louis finally decides to propose to Harry after a year together. He just knows that they are meant to be. They've come out as a couple to the public after about a month of being together. They're on their second tour now promoting their second full-length album. But something unexpected happens during the tour. One of the boys becomes sick and it could end up to be just nothing and they'll turn out well but it can end up to be very severe and possibly fatal. Who will it be? Will it change One Direction for good?
