While I liked the concept of the storyline when I read it in the details, so far, it fails to deliver.

The female lead is so irksome and annoying. At first, they made it seem like she could hold her own physically but that soon goes out the window.

I'm not impressed by the way she keeps calling the ML constantly for help even for the most stupidest lovey dovey crap. Then of course, she rendered completely useless when she supposed to catch a criminal or when faced against one.

The way the female lead acts all speechless or dumb when faced with her boss (who she idolizes) is so ridiculous that it's embarrassing and cringe-worthy. It's pathetic.

I don't know if we're supposed to look at her as an immature and childish woman or just a plain naive one. Even her "job" is pretty useless. I really don't know what's the deal with her co-workers. They're just there for them to pity her. They're so unimportant and add nothing to the story. You can take them all out and nothing would change.

As for the ML, I dunno why he's described as an antagonist who is supposed to be "evil"... the show doesn't really portray him like that. He's supposed to be cunning and manipulative but he's more of an egotistical jerk wannabe. Are you honestly supposed to believe he's really from another time or fantasy fiction? We're just supposed to somehow dismiss it and believe he's just sooo smart.

As for the secondary characters, the boss pining after his former secretary is uninteresting. She looks a lot older than him that they seem so mismatched. It's like he just comes to work just to "stalk" and spy on her.

Right now I'm at E6 and I'm very close to dropping this if the FL's character doesn't improve or mature.

So far this is just a fluff and light drama. No real depth in any of the characters.

Update:
I watched up to Ep8 and couldn't get back into it. Not worth wasting any more time watching this. I'm starting to realize that most CDramas are showing FLs as either really dumbed down or overly bitchy. You can't have a strong female lead who doesn't take crap from anyone and can hold her own. As an international viewer from North America, I'm finding myself in general turned off by a lot of cdramas and just like this one, it's just not worth watching.
