I have not read the manga nor seen any adaptation of this, so take this review for what it is.

It started off pretty good with good comedic execution, but about the 1/3 of the way through it just started to drag and drag and drag at a snail's pace. I started watching at 1.5x the speed and it still dragged, e.g., there was a scene where FL counted the 520 flower bouquet from the ML...seriously?! Like I want to watch someone count flowers for a couple of minutes?! It dragged out even at 1.5x speed...and there were other parts like that...walking in the rain...ugh...

I'll start w/ the bad as I'll need some time to think about what was good...
- FL started of strong and fearless, but eventually became indecisive, weak, annoying
- ML character was mean, abusive, a jerk, selfish, and though was supposed to be financially smart and had a plan to re-conceptualize Daoming hotels, he couldn't apply this to change the fate of the company nor himself
- Side romances were unnecessary (I skipped through them...didn't see the point)
- Too many flashbacks that re-hashed stories that already made the drama drag on, on it's first pass
- Too many episodes - could have finished the entire thing in 20 episodes and make it more exciting
- I've seen better dramas portraying poor girl/boy romance with rich boy/girl
- Halfway through, it seems the screenwriters were using every trope possible to keep this drama going (kidnapping, fasting protest, weird wedding, ugh...)

The little bit of good
- Started off strong with good comedic execution
- I guess that's it...
