I don't think the author realizes that kidnapping someone of katarina's nobility (not to mention being the fiance of a friggin prince) would be enough to get a army to literally eradicate a noble house in historical senses, they are playing this card a little too much.
As for the harem god in a romantic title, Katarina too often becomes a maiden in trouble. Are girls really fantasizing of being saved even in a works with the direct or indirect OP MC?
Geobro, who tf lets a lady walk all by herself in the night?! Like how many times have we not saw a guy walking a girl at night to make sure she gets home in anime/manga. For someone whose supposed to be her fiancé, he is written poorly. Hope he gets his development.
