The Long and the Short of It
I look up to him.
Go ahead, laugh. Everyone does; I've grown used to it. Your laughter does not change the truth.
From earliest childhood, I understood my duty: to serve my lord, in whatever capacity he required. And I have belonged to him for my entire life — boy, man, and vampire.
In our younger days, I was his constant companion and personal servant. We studied Latin and history, and practiced music, swordcraft, and riding together. We were inseparable.
As we grew older, our relationship shifted somewhat. He had royal blood, I was but a commoner. My love and fealty were unshaken, but his view broadened and changed as he learned the scope of his fate. But our bond remained. And when he was transformed, I was there for him — his most devoted source of nourishment. I served him thus until I grew too old to sustain him sufficiently... and was prepared to be banished from his service, having outlived my usefulness. But my lord held me in affection, and valued me for more than mere sustenance. He graciously granted me the boon of eternal service. And I have spent the centuries since then showing my gratitude.
Over the years I have acted as squire, butler, valet, and equerry. Today, I am his most valued man of business. I am always at his side, fulfilling whatever role is required. Yes, I am small of stature. But my heart is that of a giant. And it is completely devoted to him.
For whatever reason, I had never given him much thought before, except perhaps as a source of humor. You've given him an eloquent voice and a purpose beyond flunkie. 
That expression on his face had a sort of dignity behind the adoring expression. 
And yes, there is history in his look... but there's also a bit of wry humor. I'm glad this version of his history rings true to you! 
Glad you liked it.
