This series feels kind of... not retro, but like something that would have come out in the early 2000's. The art style, the paneling, the pacing, even the unrelated oneshot included in the volume all scream "2001 shoujo manga". Mixed with the more modern villainess isekai genre makes this series interesting. The story isn't especially good, but the execution is refreshing (and maybe a bit nostalgic for people like me who have been reading shojo for decades now lol).
