Manga recs please~

fantasy, a story that's in another world :)

hmm try beware of the villainess, if u read it already thats too bad :')

as I usually avoid isekai with a lot of drama (like those in the chinese historical settings with political struggles) here are some that are (mostly) drama free or rather fluffy:

the ending was a bit abrupt but still quite nice

http://www.mangago.zone/read-manga/seijo_no_maryoku_wa_bannou_desu/
quite slow pace but enjoyable

has only 13 chapters at the moment but volume 4 just began so I have high hopes that it will continue

the MC is quite oblivious but still worth a try

drama incomming but I hope it doesn't end bad

fluffy manga but still not 20 chapters....

sorry these are all that came to mind as isekai mangas with female MC and more than 20 chapters

The Justice of Villainous Woman is good - BUT it's not complete ( and I think is awaiting updates on here)

i dont know if this is isekai but try http://www.mangago.zone/read-manga/cheating_men_must_die/
