How convenient that the girl who was a history geek was transported back in time to the period she knows best.
How convenient that she encountered the one person who would actually believe her and somehow employ her on the spot.
How convenient(for the reader) that her new clothes still somehow have a miniskirt and she didn't even have to change her hairstyle.
How convenient that she just happened to have seeds on her person on that specific day, and she apparently attends an "agricultural school", and her first job was to improve farming output of a village.
Women had no rights and were treated like dirt
Proving once again that there is nothing more ahistorical than a manga with a "historical" tag
