Any new-ish villainess manga/manwha??? I think I've read most if not all of the good one...

I assume youve read The Holy Grail Of Eris?

Yep, also I Want to Be You Just For A Day

Have you read "may I ask for one final thing " and this http://www.mangago.zone/read-manga/jishou_akuyaku_reijou_na_konyakusha_no_kansatsu_kiroku/

Awww I've read those too, but still, thanks~

Nah it's fine (￣▽￣)
