Lost. Nastu x reader fairy tail

(Y/n) (L/n) is your average teenager with a messed up past. Alike a fair few other members of the fairy tail guild, (Y/n) has been found by a guild member, nurtured back to health and has decided to join the guild.
She is an elemental dragon slayer, making her the 5th dragon slayer in the guild. She's pretty casual however there is one thing different about her.
And that is Nastu dragneel.
