This manga has a lot going for it. It is one of the early innovators of the Otome-Isekai genre (It's novel came out in 2014!!!) and even then it was throwing a fun yandere twist onto that genre that had been based off of works like the Angelique games and Hamefura. The tone gets more serious as the story goes on, so be forewarned it doesn't really stay that lighthearted (although I suppose it's ironic to expect a yandere premise to be lighthearted when a key cornerstone of that archetype involves very dark actions). The art is competent and generally pleasant, but nothing to writehome about. The presentation/pacing of the story can get a little messy at times, but the story remains engaging noentheless, especially as a subversion of the genre. Overall, worth checking out for its historical value alone, but a generally pleasant read.
