recs pls

I want a story where someone in the story hides thier identity from the characters in the story. Main character or side character as long there's someone with a hidden identity its fine.

Something like the ml from Isn’t Being A Wicked Woman Much Better? or like the MC from Eminence in Shadow.

Any genre is fine but preferably something with little to no romance. thank you! ヾ(❀╹◡╹)ﾉ~
