So it's an ending like "Faith"? Like "Love Affairs in the Afternoon"? Where they meet and look at each other from afar but you "know" they will get together?

Why weren't you happy with the ending? They will become a couple.
Of course everything leading to that was super-disappointing, and they could have shown something more between them, but other than that, the ending per se was what everyone was hoping for. Maybe not you?

There is a problem about the concubine and Yu Ha and who is Yu Ha's father. See here:

ep.4
25:51It turns out the late Grand Prince Geum Ryeong was very close to the deposed crown prince.
The ex servant says:
40:26Crown Prince did come from time to time.
40:29But no one was allowed nearby when he was having a conversation.
40:34I heard Crown Prince and Grand Prince had an exceptionally strong brotherly bond.
40:40The woman who served Grand Prince was indeed... a bit flirty.

ep.6
32:19Grand Prince cherished you a lot.
32:32The Grand Prince's woman... now follows a mere Chief Administrator, huh?

ep.7
45:21I had a relationship...
45:26not with you, but with your father.
45:30Are you talking about His Excellency Jeong Yoon?
45:34No.
45:38I meant your biological father.
45:49It is a relationship from ages ago.
46:19This is the will your...
46:29biological father gave me.

So, from all this, we have assumed it was the Grand Prince who was the courtesan hostess's lover and Yu Ha's father.
BUT:
ep.8
Yu Ha says to the courtesan (possibly his mother, but he still doesn't make the link)
32:01 You must be the one who told Left State Minister about me.
32:05 Since you are also the one who gave me the Crown prince's will.

32:39 To our next meeting... please bring the inheritance.
32:46 I mean the keepsake... the crown prince left to you.

It's easy to say that the subs on episode 8 are wrong, but I clearly hear "seja choha" which cannot be anything else than crown prince.

So... was this woman in a relationship both with the Grand Prince AND with the Crown Prince?

The original poster has only watched up to episode 3 when s/he asked the question, so couldn't mean Yu Ha because Yu Ha didn't have the money back in episode 3. He only got some money after selling some land he got as inheritance from his stepmother, who died some episodes later.
And then... He's not a relative, he's not her fiancé, he's only a boarder at the guesthouse. It is very natural that she feels burdened to take it. Especially since he seems to be in love with her, and with this he would draw even closer, and she would feel obligated to him and very sorry to have to refuse him.
At last she had to accept, but she would have vastly preferred if there were another option, and I fully understand her!

But this fact will pose a great obstacle to their getting together, and he knows she won't be happy that he's her fiancé's killer.

What do you mean she has the money? She has no money.

He he!

Cuter? Maybe. But his acting skills here are embarrassing. He certainly got better since then, but in that drama ...

Calibre is not only regarding ability, but also in, how to say, standing.
However, she's not what worries me most in the project. Rather the director and writer. Lee Sang Yeob doesn't have many more years of being male lead material (you know how youth-obsessed Korea is!), and he is finally getting recognized, after many years of only getting secondary roles. Time is running out , so every project must be carefully chosen to be both good and successful. Anyway, let's keep our fingers crossed, maybe we'll be pleasantly surprised!

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.
