My Girlfriend's Friend, Lucy. (NaLu)
Lisanna was Natsu's first love. But now that it's over and a new friend of hers is welcomed into their big family at their private school, they instantly become friends. Lucy's dark humor and vicious cruelty towards Natsu is not only what drives them together. But Natsu's urge to push her buttons is another. But they just don't know how to push each other closer, but maybe, just maybe, their interesting and crazy group of friends just might know how to do so.
