I'm going to say Dragoon, even though I could see Monk as well for you. At first, I thought Monk because you're blunt, honest and loyal; also the stubbornness and sometimes overestimating yourself added to my thoughts... but you seem to be more reversed and calm than most Monk-characters and Dragoon-characters usually are more on the blunt/honest-side as well and they're definitely loyal to selected persons, too.
