Heroine? Seijo? Iie, All Works Maid desu (Hokori)!

Melody has one clear ambition: become the finest maid in the world. Reincarnated from Japan into the kingdom of Théolas, she takes a job with an impoverished count's household and turns ordinary chores into near-miracles through magic whose absurd power she barely notices. Cheap tea becomes luxurious, a crumbling mansion is restored, and cleaning, cooking, hunting, and repairs are simply more work to master. What Melody does not know is that this world resembles an otome game and that she carries the role and abilities of its saintly heroine. Romance, destiny, and even the Demon Lord all rank below the same priority in her mind: finish the job properly.
