Do you mean the butler?
I think that that's because of his personality. He has low self-confidence and seems to also have low self-esteem. He said it himself, when he talked about how he had no hobbies or interests of his own and that he was a boring person.
And by the look of his eyes it shows that it's not because of the japanese way to lower oneself/being humble. That look clearly showed that he actually believes it. He believes that he himself has no worth.
And I find that terribly sad.
So I hope chef-san will give him some of that self-confidence that he lacks. (=・ω・=)
yep, the butler mostly but the other characters did it sometimes too. i think maybe sensei pick a bit awkward angle there..haha
wuuuu..so bold..haha
but i was thinking why was the character look down most of the time or it is just the angle or it is just the sensei's drawing style?
