UzaMaid: Our Maid Is Way Too Annoying!

The interesting thing is that this show takes the standard "pursuing a tsundere" plotline, moves it over into a context where the inappropriate and creepy aspects of it are put front and center, and then makes the tsundere into the central character, with agency and a life outside this whole attempted-relationship nonsense. Notably, while Tsubame oversteps boundaries in comedic ways, there's never a sense of *threat*, in-character or out. This show walks a careful line with excellent results.
