Harem nerfs good isekai anime

It's genuinely so rare to find an isekai where there is no harem, mc has a goal that makes sense, plot that is thick and interesting, side characters that aren't just there for decoration, has an actually meaningful romance subplot, characters' personal growth and good animation.

There are amazing light novels that could easily be adapted into animes which will check off all these boxes but instead we get to see sum "reincarnated into world lvl 3 now I gotta marry 50 princesses and have 100 babies to win against the crazy system" sorta slop 💔
