Hanzo Shimada

Respects your way of life wholeheartedly

Treats you with the same respect he would anyone of nobility

Except with extra affection for obvious reasons

If there's a certain event or action of your royalty lifestyle that he's not sure about, he'll ask and try to work it out properly

He's already a pretty noble man himself (if not a bit rough around the edges for obvious reasons regarding his past) so it's not very difficult for him to intertwine his own way of life with yours

A gentleman

A mildly hotheaded gentleman but a gentleman nonetheless

Loves pampering you by surprising you with gifts

Gives you several royal pet names (queen/king or prince/princess depending on your preference, my liege, etc)

Once bought you a crown partially as a joke and partially because he thought you would look pretty with it on

It's now one of your prized possessions
