Let's start with the obvious, it's a 100+ episodes type drama focused on Revenge.
If you have seen one, you've most likely see most of them
The recipe stays the same: Lead will experience abuses, than when she/he lost enough will dedicate itself to Revenge . Then will find a enemy of its enemy, and 100 episodes later the vilains will get what they deserve.

If you don't like that type of drama, you probably never will.

Intro done, let's start the true review.

Story:
For this type of drama, it was pretty good.
The beginning is hard to digest but i advice you to hold on until at least the revenge path has started.
At first, the vilains are way too vilainous, it's caricatural.
The Fl and her family are weak and pathetic...
But it gets better, and at some point you might find yourself engaged in the story.

The characters evolve, the weak will become less naive and more cunning.
The bad guys will feel the axe of revenge fall over their heads.
The fact that the FL is actively involved in the revenge was truly appreciated. She does not just depend on her allies.
I also like the fact that the romance was not overbearing, the true focus stays on the revenge.
P.s: Special mention , no amnesy plot, or FL revealed as the hidden daughter of the enemy... that's quite refreshing.

Acting.
Minus one character that was too much (ML's mother) but probably on purpose, the acting was pretty okay

Music:
I won't remember this soundtrack, but at least it did not bother me.

Rewatch value?
I binge-watched this show.
Once the introduction's act was done, it became quite ok.
In a few year, i might rewatch this.
