Frozen Flame (Gratsu)

It's been a long time since Natsu Dragneel has been normal. His only family, his father igneel, has been missing for eight years, leaving Natsu on his own. After that, Natsu's flame dissolved and he fell into a depression despite everything Igneel taught him...

Gray Fullbuster is happy. He's got a good house, a good family, even a dog! Yeah, no. He lives in a run down old apartment because he barely has enough money from his job to pay for it, all of his family, except his brother Lyon who refuses to admit he's worried, is dead and he's all alone in the little apartment. But he is content with life. He is convinced the only thing you need to live is a cold drink and an ice bath.
