Dirtaria
Before Natsu was a legendary S-Class candidate, he was just a kid taking odd jobs in Magnolia. That's how he met Adam Briggs-a normal guy with zero magic, a sharp mind for logistics, and a habit of hiring a reckless pink-haired kid to guard high-value cargo. Years later, the war is over, Magnolia is rebuilding, and Adam walks back into the Guild hall with a new job and the same steady smile. There's just one problem: Natsu isn't looking at him the way he used to. Fresh off the battle with Zeref, Natsu is suddenly dealing with a brand-new kind of magic he doesn't know how to handle: romantic attraction. Between Happy's endless teasing, the Guild's chaos, and the impending 100 Years Quest, Natsu has to figure out if he can guard more than just Adam's cargo this time.
