[ The question gets Sebastian to briefly glance Haru's way, but it's smoothly followed with a gentle smile. He closes his eyes as he works, and indeed, the expression could definitely be mistaken for fondness, but that's not at all what it is. ]

Quite strange, yes. I am meant to be at my master's side at all times, since it is my duty to protect him. With what I had been told, I would worry that perhaps I had failed... It is quite strange to think about. I have never failed my master, you know.

[ But that's a personal topic, and as such, he shifts the topic away rather quickly, since it's better for him to not speak of himself. ]

Ah, it certainly sounds strange to my ears... Perhaps we have it backwards in the West, for the home is usually guarded against any and all spirits rather than welcome them.

[ But considering the more malevolent spirits (not naming names here), there's certainly a reason for that. Sebastian seems to find the idea rather charming based on how his smile shifts, and indeed, he ends up laughing gently. ]

My, but to think about it, I can only imagine what spirit may watch over the young master's manor, were that the case. [ a super messed up spirit, that's for sure ]
