Exclusivity is difficult, Your Majesty

It has been five years since I remembered my past life.
But nothing happened.
“What original story? What is that. Is it something you eat?”
Even if I do not know the world setting, it does not cause any problem for making a living.
I earn good money, and I can even handle dragons well!
I thought it would be nice to live a long and quiet life as a dragon trainer!
…Maybe because I thought that—
“I would like you to become my dragon’s exclusive trainer.”
“I am sorry. I cannot take that job.”
Of all things, I was chosen by the duke’s dragon.
I know this. I have seen it somewhere before.
The duke clearly looks like the protagonist from a novel,
and if someone like that becomes my employer,
there is no way I can live a long and quiet life,
so I rejected it without hesitation—
“I am starting to wonder how long you will keep being stubborn.”
Why are you saying lines like an obsessed man? Stop raising flags!
