This is a really good kdrama. It could've been in my TOP5 but the absurd comedy made it less impressive for me.
I am always very forgiving with absurdity in kdramas, and this one was no exception. No way i would've let so many flaws get by in a western production, yet this is the beauty of watching a kdrama. The absurd parts are so absurd that the only thing left to do is laugh, and that's ok.

I liked the ending. At least in the end some "realism" was left and the happy ending is somehow bittersweet if you think of it.

All actors did an excellent job. Every single one of them! Side characters included!
Loved the movie and other kdrama references that were written in the script! Truly hilarious! The "2PM" jokes were also chief's kiss!

I would totally recommend this kdrama to everyone used to asian productions. It's like a really good manga/anime. Half of it it's very realistic and the other half is crack humor that doesn't make much sense but we are here for it anyway.

Just one last thing. "Mademoiselle" is actually french.
