You're an overlord, meaning you go to the meetings that Carmilla runs. But, you always make sure to make it difficult for her which couldn't be anymore annoying to her. Do you care though? No..

So its another meeting, Carmilla was trying to start when you carelessly come in late. Which clearly had annoyed her.

"Did you... just now decide to show up?"

She gave you an annoyed glare while saying that, it was really obvious.
