it’s one of my fav historical manhwas but there’s not many that are like it
there's a historical manhwa called secret lady with similar artstyle.
not so wicked stepmother, is on the wholesome side with a touch of martial trauma
there's also, I will change the genre, which is more shoujo then josei.
maybe, go away romeo, though the only thing I can vouch is that she is a single mother.
Like loser/ funny mc and a sorta unique plot like no dungeons, hunters, martial arts, like a modern agency thing I don’t mind if there is or isn’t romance
