"I haven't fallen"

Yes a gender bent.

Natsu is transferred to a different school with her friends Erzo, Juvio, Gajeel, Grace, and Miro. She's been through a lot, her father went to work one day and never came back, similar to her brother. Ever since then her happy energetic expression has changed to a serious and very strong person. What happens when Luke tries to flirt with her? What happens if Luke never suspected her to be a dragon slayer and challenges her to a battle?
