Yeah, that's a very understandable worry. Some shows have managed it wonderfully, like the thematically similar Maou-jou de Oyasumi / Sleepy Princess in the Demon Castle, but as someone who's been going slowly through 'Tis Time for torture, even the manga starts feeling a bit repetitive if you try to binge more chapters in a short while.

I was shocked at how quickly Recently Hired Maid got old. On paper, that show should have been a guaranteed win for me, and the first 2 episodes it was, and then...it was just the same situation every time.
