She was good in Trot Lovers, but since then she has concentrated in her singing career much more.

I read that, other than two cameos, she's played in a total of SIX dramas since her successful acting debut in 2012. And two movies and a web drama. Compare this to her super-active singing career - there's no comparison.

It was said that there are many watchmen who are trained somewhere with the queen's money - not in the palace.

Yes, there is one, but it's obvious the SL has no chance at all.

Why are you saying this? Everything points to him so far. Of course it could be a trick on the writers' part.

Can't it have been the Watchman as child? He could have lost his parents as well.

Nah, there is zero chemistry between them, she just sees him as a friend. Unlike the other guy!

I love, love Lee Sang Yeob. But who are these two, the director and writer? I've never heard of any of their dramas mentioned. And the actress ... Couldn't they cast him with one of equal caliber?

I beg to differ that drug taking does not affect one's work. How focused and disciplined can you be for shooting when you're taking drugs? How many actors (from Marilyn to Judy Garland to Johnny Depp to Robert Downey Junior....) made studios lose millions because of being late or no-show, forgetting lines, requiring multiple takes for each scene etc?
Yes, one might refrain from taking them the day before filming, but sometimes (especially in the case of a drama where you're the main lead, filming goes on daily for a long period of time. When you're not filming, you need to rest well, eat well, exercise to keep in good shape and learn your many lines by heart.
How can you give your very best when you're a regular drug user? Performance will dwindle and eventually companies won't hire you anymore, as has happened with the aforementioned Hollywood examples.

@monstersnroses: I don't assume his motivations for starting to take drugs; this might be for any reason, I know nothing about it so I'm surely not going into that.
I do assume he loves acting (because he's repeatedly said so, and also it shows from his performances), therefore I also assume he doesn't want his career to end ingloriously.
Given this, whatever the reason might be to start doing drugs, the only explanation for his continuing to do something that may well cost him his beloved career is that he believes (has convinced himself) that he won't be caught. Just simple logic.

Can't these actors, who very well know what is at stake, be more careful with their lifestyle choices? I mean come on, how difficult is it NOT to take drugs, man? Why ruin your career, when you're one of the very best Korean actors out there, and you have so many projects lined up? Everyone thinks they're smarter than others and won't get caught.
Sorry, not sorry.

Ah, that's too bad!

No it's not the same ending. It's a subdued happy ending, implied, not really shown, but you know that they will end up together. Remember "Faith", where they just meet and look at each other? That sort of thing. Very frustrating, but still better than the Japanese version.

I didn't think so. It was more implied than shown. Just like "Faith".

But not shown in a satisfactory way. You just "know" that they met again and now they are probably going to be together.

It is a stretch to call it "historical". Romantic comedy fusion drama set in the past.

I wasn't overly impressed with episode 1, let's hope it gets more interesting. For now it's as bland as Hwarang or Joseon Marriage Agency and the likes. Nothing that hasn't been done dozens of times already.

Obviously the FL will surely end up with the prince because they met as children (people were chasing him, he lost both his parents, he was richly dressed and couldn't reveal his name). It's also sure that she will end with Kang San, the one she bickers with and there's an unpleasant start of relationship, which in k-drama is an indication that the two will become a couple. Therefore Kang San is the prince. He also looks a lot like his teenage self shown briefly.
I don't think it can be called a spoiler since I only have watched episode 1, like all of you, and I'm not the writer's cousin, so I obviously don't know the ending. What I'm saying is based on all the other Korean dramas watched so far, in the past seven years.

He's so lovable, and his acting never disappoints! But couldn't they find a better picture of him?

You can watch it again with subs on Viki. https://www.viki.com/movies/38727c-serve-the-people.
But it seems you skipped the scene after the credits.
