Hidden / Secret Identity

One of my all time favorites even if it gets heavy handed in background and bad guy maneuvering etc. The main guy is pretty much superman with the undercover reporter act. So much fun here.

A noble lady is secretly a freedom fighter

Not for the faint of heart to start a 51 episode saguek, but there is a lot of fun in the first 15-20 episodes (total guess) where she's doing the whole gender bender thing and most people don't know she's a girl. Actually, I think there are several layers of who am I deception but I can't remember it all...

Feels a little like a newer shinier version of Sungkyunkwan scandal. This one's gender bender in the palace.

Probably one of my first gender-bender style secret identity dramas and it was a lot of fun! It does feel a little dated now 10 years later, but Park Min Young is always a favorite.

Someone is (illegally) messing with authority around the school and doing it under a secret identity! .... dun dun dun

Identical twins. Need I say more?

Another identical twin one...

Apparently I watched almost all of this one but I don't remember doing so... Poor girl takes over identical rich girls place??

Secret masked freedom fighter against Japanese takeover.

Mother goes undercover as a high school student to protect her daughter.

Similar plotline to Nice Witch with the tough sister getting in a coma and the nice twin having to take her place.

Heiress goes undercover

An overwight ajumma gets magically transformed into her beautiful 20 year old self... but only for a limited amount of time

So far what I've seen, very similar to Perfume, except the overweight girl worked past her weight to become a supermodel... unless she eats more than 1000 cal in a day, then she very suddenly gains back all her old weight... Her high school love can't seem to recognize her new skinny self.

Heiress undercover... likes to work at a grocery store... that's about all I remember right now about this.

I've never even tried watching this one yet....

Another identical swap places dun dun dun

High school kid has to pretend to be his identical older brother at work

I dropped this at 16/20 though I know how it ends. It feels like an inferior Healer. The guy with background stuff revenge undercover blah blah blah. I think the only thing I liked better was Park Min Young's character. However, she and JCW look much better together

This girl has multiple undercover identities lol. She's actually a rich girl who pretends to be a poor college girl who is secretly the leader of the MCs fan club and also secretly his crush when she dresses up, etc, etc. Lots of fun.

A princess whose family was wrongfully murdered goes undercover to seek revenge... if I remember right. I never finished watching this, though I read how it finishes. I made it more than half way but it descended into that historical sob story hell I'm not a fan of.

Main girl is the missing princess, also dresses up gender bender, etc. I watched more than half of this very long drama so I did find it good. I plan to finish it some day.

Twin sister pretends to be her brother

The girl is secretly a mermaaaiiid :)

The clown somehow looks identical to the emperor... and might end up being a better one when he takes his place.

The vet is actually an assassin?!?

So, a con man didn't realize his girlfriend was a cop until after they got married. But it was too late to back out or tell her his profession at that point hehe

Twins switching places. One of the few Thai dramas I've completed without a lot of pausing, skipping, and pain.

Two cops go undercover as a husband and wife :D

A yakuza next in line actually wants to be a teacher. Her skills come in handy when she's dealing with difficult students.

You mean that guy was the prince??

She's the lost princess and also dresses up as a man.

Housewife who can secretly kick ass (she used to be a special agent if I remember right)

In this one, a girl in need of money, pretends to be a high tech robot.

In this one, a robot is masquerading as a human, but then the real identical hooman comes back...

Girl goes undercover as eunuch in the palace to get back her money...
