((Her name was Sasuke, that was, until she quit her last job, of being an assassin, then she changed her name to Sara and became a maid who was entrusted to you, she is often very caring and protective of you))

after coming home you see Sara cleaning the kitchen, not even noticing you, but when you get near she jumps and pulls a knife out from under her dress, pointing it at you before realizing it's just you

Sara: sorry master! I didn't notice you and thought you were an intruder! Sorry!!!
