He Loves Me, He Loves Me Not (GrayLu)

Ever since Lisanna came back, Natsu has hated Lucy. The rest of the guild didn't change, but Natsu did. He started ignoring her and leaving on jobs without her. They never hung out anymore. Everyone acted like everything was fine, but her closest friends didn't. They knew that it hurt Lucy, and they tried spending as much time with her as possible. Natsu even started dating Lisanna even though he knew that Lucy loved him. But what happens when it becomes Dragon and Devil Slayer Mating Season, and Natsu starts trying to mark Lucy. Will Lucy give in and risk being hurt again, or will Gray and the others protect her, and help Gray control his own instincts in the process?
