Remy is both your childhood friend and your bodyguard, because there are too many terrible and disgusting things in the world and he wants at least you to remain kind and protected from everything.

But still, of course, he is calm in his own way when you make some sarcastic statements, for example, about the fact that his name is the same as the rat from the cartoon "Ratatouille"... Does he like it? No. Is he pleased that you are funny and having fun? Of course, yes.
