I'm thinking she is the actual female lead and that her strife with the Princess will be of a romantic nature... kind of a raw deal for the IRL figure without whom Sado would probably just have been a dark footnote in Korean history. I'll ask this again, but why can't men in sageuk be loyal to their wives instead of indulging in transplanted Cinderella stories?!

"I don’t think she’s quite at the level of some of her peers like Kim So-hyun..."

I always tot she is better than her, well then again its my own personal opinion I guess. Btw, this drama seems to have a line of fantastic actors and actresses, hope they can meet the high expectation :)

I love her so much.
I am glad hear her will be take female lead role, and its saeguk, i love her with hanbok.

Can I request Yeo Jin Go for this drama? hehehhhe

just curious - what exactly does tapping into her emotions and digging deep entail? I think what this entails probably differs for different people.
I've seen some actors do something that looks like it, but it looks well exaggerated, and then some actors who are said to not be showing enough emotion or something.
Eh, I dunno.
I can't be a judge of whether or not she's "better" than Kim So Hyun seeing as I haven't seen a fair proportion of her massively diverse body of work (nor of Kim's), but I heard she's quite the flaming beacon in Flames of Desire. And I've realised from before that I can't make a fair judgement on people's acting ability just from looking at one portion of their body of works. Or from works that are rubbish that would basically make anybody starring in it suck.

Love her but it's sad that the producers would rather use a child actress who isn't even in high school yet, rather than one of the dozens of talented young 20something actresses who could truly shine in a role like this.

On the bright side, she can actually act and isn't some idol, Han Ga In or Jin Se Yeon (my two new benchmarks for actresses who suck)

I agree with some of the comments here that I've always thought she was better than Kim So-hyun. Maybe I'm just a bigger fan of hers but she always manages to evoke emotions out of me the way KSH can't.

In any case, I just hope she isn't playing a concubine to Sado because pairing her up with LJH is just creepy. He's 30 and she's half his age + a minor. That's just wrong. On the other hand, PEB? I had to look her up cz I don't remember her but she's also a little younger than my expected age range. But since the drama is focusing on the men, they might've preferred to give some up and coming actors a chance.

Is that a trend today? ahjussi romance.. :3
Kim So Hyun with Chun Jung Myung, Kim Sae Ron with two Infinte guys..

and i though they were sticking with the history why create a fictional character? >.< i'm still bitter, i still want Kim Yoo Jung and Lee Min Ho '93 in a drama together as lead..

That's just your opinion! BUT to me, Kim Yoo Jung is my most favorite young actress of all!

I just see all who put young actresses into a comparison are cruel! javabeans, you should leave them alone! They're just teenagers! Don't hurt them like that!

Yoojung Fighting!! YOU'RE the best! ~~

I hope writer Yoon Sun-Joo is up for the challenge. She has a boat load of raw talents in her hands. I hope she'll make good use of them.

I hope Park Eun Bin takes up the offer too, she's amazing!

Sageuk is so not my thing but this show sounds like it's going to be a veritable tour de force of fabulous acting. I might have to check it out for that alone.

I ALWAYS THINK KIM YOO JUNG IS THE BEST ONE AMONG THEIR AGES! I JUST LOVE YOO JUNG'S ACTING AND IT TOUCHES MY HEART BY THE WAY NO OTHER CHILD ACTRESSES CAN! I LIKE KIM YOO JUNG BETTER! ^^

IMO, comparing Kim Yoo Jung and Kim So Hyun's acting is like comparing Ha Ji Won and Son Ye Jin's acting. I just cant say who is better than who since they are all GREAT in their own way and I love each of them to pieces.

But I think So Hyun somehow has more mature look than Yoo Jung. While Yoo Jung just gives me girl-vibe, I feel im-not-a-girl-not-yet-a-woman vibe from So Hyun. Plus, maybe its just coincidence, but in most of Yoo Jung's dramas Ive watched she was always the child/early-teen version of female lead, while for So Hyun Ive caught some where she played mid-teen daughter of the main lead ---> thats why I tend to think about Yoo Jung as a "child" actress, So Hyun as "teenage" actress, though they are at the same age.

About Secret Door, since its a sageuk no need to worry about "romantic scene" if there ever be. And judging from how much Im enjoying High School Love On, I think Im fine with huge age gap or underage thingy, keke.

Kim Yoo Jung, Kim So Hyun, Kim Sae Ron, Kim Hyang Gi, wow those Kim ladies are rocking my screen when they are just 14-15!!! Oh, cant wait to see more from Seo Shin Ae and Jin Ji Hee too ~^^~

Javabeans has bias! She usually give her bias in the articles! So, just for fun!

Nah.. Though I like KSH, I think KYJ is muuuuch better!!!!!)))))

Always thought there was more of a natural charm to Kim Yoo-jung's acting style over Kim So-hyun's, which I like more. Kim So-hyun's projects have allowed her to experiment more in genres and range though, which probably gives her a little of a head start in becoming a really good actor. These two are definitely on their way. They'll be fantastic in leading roles. Can't wait already! Ha.

I usually just read and not bother with making any comments.
However, this time, I can't resisted. I do not agree that KSH is a better actress. In fact, I don't quite like her acting. KYJ, on the other hand, is very natural and charming. To each their own.

I have to say that if we’re talking purely acting skill, I don’t think she’s quite at the level of some of her peers like Kim So-hyun, because she hasn’t figured out how to tap into her emotions or dig deep in her roles

I'm going to politely disagree with this statement. Despite her tender age, I think Kim Yoo Jung is one the best actresses out there and outshines everyone around her. I'll watch anything she's in, even if the drama/movie doesn't live up to her capabilities. *cough* Golden Rainbow *cough*

Am I the only one that doesn't see Kim Yoo Jung's appeal/talent? Her acting doesn't seem to evoke much or any emotion at all for me. Oh well, everyone is different! I am hoping in the future both girls are able to grow into lovely actresses :)

i like acting of both actress kim yoo jung's and so hyun's but kim yoo jung has made me teary with her acting which kim so hyun never did. i guess kim yoo jung's acting appeals more to me

I have watched both Kim So Hyun & Kim Yoo- jung. KMJ's performance moves me more. I prefer Kim Yoo-jung. Even in variety shows.

She fits sageuk dramas, maybe because of her classy beauty look. But I would like to see her in a modern role too.
And with the Kim Yoo Jung vs Kim So Hyun, nothing to compare, they are two different type of actress. The only thing the have together is they are both in Sidus company, and apears in Moon and Sun as rivals.

For me,
KYJ is beautiful and KSH is pretty.
KYJ plays roles where she expresses emotion, KSH plays how to hide emotion.
KYJ fits sageuk, KSH fits modern dramas.
KYJ fits movie more, KSH fits drama more.
KYJ looks babyfaced but has curves, KSH looks more matured but has no curves.

I like them both but seen more of KSH. I think Jin Ji Hee is good two but the 2 moons outshined her.
