This is a Natsu x reader, English is not my best language and I am not one of those amazing people who make those god works of art but I still hope this is good enough for you
I will follow some of the fairy tail story line but not all I may skip some or replace them with something of my own
I will add some smut later if I feel like my writing is better and can give y'all a good one
