After two or three a bit slow and sometimes boring episodes, the drama finds its pace and presents a rather intriguing and well-presented story line.
Yeo-hwa lives as a widow with her in-laws after her husband passed away on the day of the marriage before she even met him. She has to be obedient and cry at the shrine all day long, that's basically her life. Or it should be her life, but fortunately, this historical K-Drama gives us a strong and intelligent main character, as Yeo-hwa is skilled in martial arts and roams the streets at night to help the ones in need and fight for justice. Sooner or later, she has to face the law, because even Joseon has a police force. Luckily for us (and for Yeo-hwa), the law comes in form of the handsome sergeant Jong-won. After a while, they find themselves on the same side of a bigger story that revolves around the death of Jong-wons family, the disappearance of Yeo-hwas brother and a tragic incident in the king's past.
As I said, the series needs a few episodes before it becomes interesting. After that, it stands out as a balanced, nicely written historical drama. From all KDramas I have seen so far, "Knight Flower" is in the top of having well written characters. Normally, there are quite a few I find boring or annoying, they scream too much or are way to toxic or just stupid and silly, but in this series, everyone has their place, everyone feels well-developed and believable, even the villains are not just there to be villains. Most importantly, the main characters are smart and act accordingly, not rushing into things just to create drama and plot points. When they do, it's understandable and still fitting for their character.
The love story is slow, it works with gazes and carefully crafted scenes of quite affection that can be hotter than a full on make out session. The chemistry is tangible. Over the just 12 episodes, you find a nicely paced drama with an enjoyable cast, quite a bit of humour, an interesting plot and two refreshingly strong and independent main characters.
