Service Android

A girl who lost her parents in a battle is gifted with an service android by her grand aunt.
But there's something strange: the android is strangely familiar. Who is he?

"G'day my lady! Did you have a good night's sleep?" the android greeted me.
"Well what does it look like?" I asked back, irritated.
The android turned his back to see my face so he could analyze my face.
"I suppose not," he responded.

I got my android as a gift from my grandaunt after my parents passed away. Thankfully my parents wrote a will so I could inherit all my parents wealth and so on.
