In summary:
This is currently my favourite romance drama, which says a lot, because I generally have an issue with most romantic dramas (e.g. coffee prince, it's okay that's love) .
It is kinda a parody of historical romances, and therefore more light-hearted than other historical dramas,
at the same time it does have some real tragic drama in it.
The female lead is really funny and she has great chemistry with the male lead, they have really sweet scenes together.
The ending is confusing; however it does make you interested in wanting to know more.


----------------- Longer version ----------------
I usually find most drama's not that fun, because they in general romanticise toxic behaviour (over dominating male lead, being too possesive, and/or a female lead which acts too much like a child, underdog behaviour). However, in this drama I found the interaction between the ml and fl very sweet. The male lead is really caring, in a not too overly possesive way. Ofcourse, the ml is in the beginning a bit cold, however, he actually has good reasons... like actually good reasons, not some cop-out 'boohoo I have a bad childhood, so I am justified to be a creepy jerk' reason.

The female lead is really fun to watch, she is actually funny (unlike ashes of love) and really goes into her character. She has to play having two souls into one body, and she really pulls it off. I think in general all actors fit their roles well, they have a certain likeability factor, which makes it fun to watch them.

The story is not super complex, but is well written. After every episode I wanted to see the next one, I cannot remember it having any fillers, every scene builds on to the next one. The ending is confusing though, but it had some interesting potential for follow-up seasons.

I really wish for more romance dramas like this one, but I have not found them yet.
