I love you, Flame Face (NatsuXFem! Reader)

As a child, (Y/N)'s older sister was part of the famous Fairytail guild. She spends a lot of time in the guild with the other children seeing as her older sister was her only family and she went out on jobs a lot. She got on well with most of them except for Gray. Another person is added to the list when a pink haired dragon slayer entered the guild. After years of a three way rivalry between them (Y/N) begins to feel... Very strange around Natsu.

I don't own Fairytail or any of the characters mentioned.
