Disguised Lead Characters

Hi, MDL Community!

I need a drama wherein the lead character has to disguise himself like in Healer and Bridal Mask.

If you know any good ones, kindly comment below. Thanks so much! :)

Definitely you must watch Cruel City...

Hmmm City Hunter?
CH & Healer are quite similar, thou the plots are different.
Definitely watch Cruel City!

Also Hero (2012), although I guess I can't comment on how "good" it is, since I never quite finished it...it was good up to where I stopped, though!  Someday I'll watch the last couple of episodes :)

Iljimae
The Joseon Gunman
The Scholar Who Walks the Night
That Winter the Wind Blows
City Hunter
Time Between Dog and Wolf
Spy

Come back Mister - not really disguised but came back from dead to a different body
