First thing that comes to mind Masamune-kun no Revenge, but I don't think there's any female butler in this but then again it's been years since I watched this. Lmk if it this one

Servant / butler same diff.

You have great Donor stars.

hated that manga/anime.

it feels like the writer just started a trope and didn't even nkow where they were going halfway through. so they started contriving stuff to keep it 'interesting'
