After watching 3 episodes it just feels to me way overrated. You can tell the production and the casting are pretty good from a get go.
1st episode was pretty hooking and it felt so refreshing, relationship between Main leads felt so mysterious and I was actually wondering what really happened between them whole time, because they were introduced in a way that you didn't really care about others that much. Comedy also felt pretty fine, not overused and not forced. It felt like you've skipped 10 episodes from this drama and lost in the middle, that mysterious introduction actually made me want to know more about them and their relationship. I'd say this was actually pretty good idea and hooked a lot of people with it but sadly it just got worse from there.
Basically this drama has no Prologue but we only get to know Main Leads in the overly repeated flashbacks which felt so random and unnatural. It only leads to more and more confusion and just like salt on the wound, we get the toxic amount of cliches: sudden terminal illness, a love triangle that is pretty questionable, struggle of power. It just feels frustrating when something makes no sense and the more you watch it makes no sense even more, that's how it felt watching this drama. Episodes just felt longer more you watch, feels dragged too much. I don't know, I'm just not buying circle jerking between side characters, they look more important than main leads. These 16 episodes will probably feel like 60.

I can be wrong and I just hope this drama will prove me wrong.
