I would be far more excited about this if L wasn't the lead. I am a Kwon Nara stan, I maintain she was the best part of Itaewon Class. L is a mediocre actor and he holds no special place in my heart, so he acting actually bothers me. Meh, I hope it is good because I also really really like Lee Yi Kyung.

Has there ever been a sageuk damo who HASN'T gone undercover as a gisaeng? I am surprised they don't issue a fancy hanbok and head piece as standard regulation along with the requisite headband. Not that the other sageuk cliches are ignored -- in fact, it seems the show wants to check all the boxes: "genius" protagonist, heir vs. illegitimate son rivalry, pile of mush/chatterbox servant and confidante (hero is not a royal so this character is not a eunuch). At first blush, i wonder if good execution would be enough to ave this one...

This is a good role for Lee Yi-kyung. Hopefully he can help L deliver a good performance. Kwon Nara is also a plus for this show. I will give it a try when it comes out.

I has been reading "comedy drama New Secret Royal Investigator" and remembering Stephen Chow´s Royal Tramp.

I would have been more excited had Lee Yi-kyung been the lead and L his servant. :(

Lee Yi Kyung has been a lead before so let's get him a lead again please 🙏

Tho I'm not averse to seeing him in another comedy

One bit of casting that caught my eye is Lee Tae-hwan. I thought he was terrific at age 19 in PRIDE AND PREJUDICE (2014/15) (5 stars). I have only seen him in one other drama: W: TWO WORLD APART which I enjoyed. I am looking forward to seeing him in NSRI.
I see that he has sageuk experience being part of the cast of HWAJUNG (2015) right after P&P. I have not seen it and at 50 episodes I probably won't get to it.
Any comments/memories of LTH's performance in HWAJUNG?

Sigh... Lee Yikyung was probably better in that Hotel Del Luna faux sageuk cameo than L will be in this entire sageuk.

I’m also not that fond of Nara and Lee Taehwan, so the likelihood of me giving this a miss is high :(

Am I the only one here wondering why Cat, L's furry doppelganger in the aptly-named MEOW THE SECRET BOY isn't acting in this drama? @bbstl's cat is not pleased, I can tell you that.

The cat population is woefully unrepresented in the current crop of dramas. Something needs to change in the industry, to reflect the true picture.

And, in case you think I am exaggerating, I would have you know that I consulted my neighbour's tabby cat, Tabs, and its distant cousin, Alley, and they are NOT happy as well. @eazal is nodding in approval. @wishfultoki and @leetennant feel as strongly as I do about this. And @ndlessjoie, @poliwag and @diana-hansen, are equally passionate about this meowst troubling issue, when they are not otherwise preoccupied with debating the (non) existence of hair follicles on SSR's kairostic chest.

I love most of this cast! A must watch for me!

Sageuk you say? Emm...I don't know~
I just finished "Tale of Nokdu" 2 days ago (I know..late) and I'm having very much intense JDY withdrawal since then. Actually No! I was in crisis WHILE watching the show too. Like I always say, Sageuks are dangerous for fangirls like me...😄

this sounds so fun! hope we don't have to wait too long for it to air. i like all of them so it will be a fun ride. i think L is improving every time he acts and his last one was bad for me cause the story and execution was bad.

Lee Tae-hwan again as younger brother, jeleous of his older brother. (Or was he the older one? I don't remember much of his character in WWWSK). L's character sounds like slight variation of his character in Ms Hammurabi. I am in mood for light-hearted show, I will give it a chance for Lee Yi-kyung and Kwon Nara.
