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?
