Isekai trash-panda here, making my report after my latest dumpster dive.
This one has a very strong first half, but leans too heavily on the genre staples in the second half. A bit too trope-heavy, but overall it's an enjoyable read. It doesn't outstay its welcome and ends after 3 volumes, which I feel is quite enough for the setup and plot-building that was done. It would have to be much more character and development heavy if it should last much longer.
Overall a good read but with little to no surprises, it does the otome-isekai villainess-is-the-hero entirely straight without deviations.
