As the two most popular boys in school, Sehun and Luhan have always seen each other as rivals.With one leads the M pack while the other rules K, they get along as much as water and fire do. However, even rivals can become lovers, cant they? Foreword  This fic is my first hunhan fic, and it is highschool!au Well I had this idea because their birthdays are so close to each other and it is kind of amazing :)  special credits to ♠MrsUnic0rns Advertising Shop for advertising
