Tom has answered Sumaru's curiousness with that one sentence, he felt better now that this man wasn't just ignorant. But genuinely did not know of samurai, and how they worked. But the once Yamataian, now Nekovalkyrjan was unsure that he was the best candidate to represent the samurai order as a whole. Never the less, he decided to try and explain it the best he could.
"Well for most samurai, they are born into their lifestyle. They are brought up with duty and honor as their guiding principles. So a life of servitude is normally their desire, and defending the empire's imperial family and it's codes is a very honorable and important duty, so such a service is a very fulfilling thing for a samurai who's whole life has been preparing to fulfill such a very integral duty."
Sumaru's own words, as well as Tom's desire to settle reminded him of what he was brought up to do, what his sisters had taken so much of their time to install into him. He was born and raised to be a devoting and perfect husband (by their standards). It was so surreal that he had so long ago left that life behind, and now here he was sitting as the only remaining male Neko in the empire, and a samurai to a Ketsurui princess. Even though he had left that desire long behind in his training, he still felt somewhere deep within-- that boy who just wanted to have a loving bride to cherish and hold. With that he knew that somehow that must be how samurai must feel, that no matter how hard they would try, they would still long to be a glorious knight in service to the empire.
After snapping out of his internal delving, which took much less time then it took him to take a breath, he smiled slightly. "But that's not to say that each individual does not have their own dreams as well, I'm sure that other samurai have dreams that coincide with their lives. As I've personally met many samurai who have very diverse wishes, one of my teachers still competes to become one of the best flower arrangement artists in the entirety of the empire," Sumaru chuckled lightly, still finding it to be quite amusing.
"As for my dreams, I am sure they are as selfish as yours. I dream to be by Sora-dono's side for as long as I exist, in body or spirit. I also desire to see her grow and live out her dreams and see to it that her goals are met. I might even be more selfish, because I had made up my mind to become her samurai before she had made up hers," he trailed off and paused for a few moments stairing off into the water, "so yes, a samurai's life may seem much different, but it is all relative to who you are and where you come from."
He looked back up at the juni with that slight smile still on his soft features. "You have a beautiful dream Freeman-san, no matter what happens in your days to come. Don't let anything or anyone take it away, do like samurai and defend it with all of your might, okay?" he offered a more friendly smirk as he said that.
