~First Book of The Illness Series~ Natsu Dragneel was in his last year in college about to take over his father's company, Dragon Inc. Everyone thought Natsu was a cold-hearted person, he was harsh to his friends and even random people he just meets. There was a reason Natsu was like this. That's because his childhood best friend and secret girlfriend Lucy Heartfilla were sick with an invisible and deadly illness. Lucy got sick at the age of 9 years old she had met Natsu when she was 5. Her and Natsu always had been close and he was the only one who could calm her before her illness got too bad. What happens when Natsu's stalker finds out about Lucy? What happens with Lucy's illness takes many turns? What happens when Lucy can finally go outside once again? Will Natsu let his friends finally meet and know about his girlfriend?

(Y/N) (L/N) has always had a crush on Natsu Dragneel, the Fire Dragon Slayer. Even though she's only 10 years old and Natsu is 18. But when he and the other strongest wizards in Fairy Tail disappear for 7 years, stuck on Tenrou Island, what will happen to those feelings? During those 7 years, (Y/N) becomes the strongest wizard in Fairy Tail. They may not have been able to keep their amazing guild hall and unable to keep many guild members, but they manage to pay rent most of the time for the shack called their guild hall. All thanks to (Y/N). She takes on almost all of the jobs giving 90% of the reward to the guild to pay for the rent. She even trains all of the guild members, improving everyone's skills. When the Tenrou Team comes back, what will happen between (Y/N) and Natsu now that they are around the same age? - - cover by ; @revejb --- WARNING!!
