@Kuntatooooo this series is not something you will easily find in the shoujo manga specially not in the villainess subgenre.
Whats different:
- The villainess is not a heroine in disguise who wants to save everyone.
- The heroine is not a villainess in disguise who wants everyone to submit
- The prince is not a clown who only serves to glorify the villainess
- The capture targets have character arcs outside the villainess.
- Magic and fights are barely relevant, just a subplot to fill some explanations.
- It knows when to quit, after the first arc it just end happily
- The villainess is not an uber genius who knows how to build modern technology
- No japanese food subplot or japanese glorification whatsoever.
- Nobility ranks are actually relevant
- The villainess doesn't get a reverse harem
- Villainess is not dense or stupid, she knows the prince is in love but has another reasons to not accept that love
- Prince and villainess get together early and fix misscomunications through talking
Whats similar:
- The heroine is a love villainess in disguise who selfishly wants to hoard the affection of the capture targets
- Reincarnators are unable to differentiate what words people in medieval ages were acustomed.
- Medieval ages are glorified
- Everything is shown through the view of elite nobility who are unaware of any real world hardship.
