Exclusive Contract is Difficult, Your Grace

Of all the dragons to choose from, I had to be chosen by the Duke's. It's been five years since I regained the memories of my past life. And yet, absolutely nothing happened. "The 'original plot'? The hell is that? Is it edible?" Who cares about the plot? It's not like it affects my daily life. I'm making good money, and best of all, I get to play with dragons! All I wanted was to live a long, quiet life as a dragon trainer! ...Was that me just asking for trouble? "I want you to be my dragon's personal trainer." "I'm sorry, but I can't accept." Of all the rotten luck, to be chosen by the Duke's dragon. Ugh, I know this setup. I've seen this plot before. The moment a guy who looks like he walked straight out of a novel becomes your boss, you can kiss your quiet life goodbye. That's why I shut him down flat, but— "Let's see just how long you can keep this up." Why is he spouting lines like some possessive male lead?! Stop raising flags! Stop it
