Dramas like healer or kill it where the lead hides their identity

Hi,

Are there other dramas like healer or kill it where the main character hides their actual badass real identity?

Bonus points if they pretend to be weak in some scenes.

Thanks!

It's been ages since I saw it, but Pinocchio. The writing is very much a "small world" as in, everyone knows someone or knows someone who knows someone, so it requires suspension of disbelief, but certainly, compelling undercover revenge.

Circle. I admit, I haven't finished it yet, but it's very thrilling and there's a lot of hidden identities, and overall, really good story.

Mr. Sunshine. Historical, and not necessarily accurate, but beautiful cinematography and production value. The main lead is very capable, and his hidden identity was one of the biggest hooks (for me).

Hidden identities are one of my favourite themes, but good ones are few and far between. I know of some more, but they're more romance, or simply less compelling, with far less action than the two examples you listed.

MCs hiding their actual badass real identity is one of my favourite tropes :) Hope you find something you like!
