This is a stupidly funny story. I love the otome setting, which is kind of unique regarding the isekai genre, and the fact that is a reverse harem works for me. Katarina is really stupid, so depending on the reading she can become quickly dislikeable or not, but for me she works for now. However, the way the prose goes is really similar to a fanfiction (a lot of repetitiveness between her thoughts and the rest) so if that is not your cup of tea, I'd enter this light novel with caution.
