***May cointain spoiler***
I changed my rating to 5/10 because I can no longer take how cheesy and ridiculous the story is.
I hate how they are pitting 2 women over a man (as if he is some great reward). More than 10 episodes with just two women plotting against each other to win a man.
La El's revenge waa supposed to be about what happened to her family, her hate was supposed to drive her mad to the point of not caring about anything else except revenge.
Yet, the story only shows them fighting over chairman's love and to justify her action- they made Sora (the wife who supposedly love her husband so much) cheat on her husband, so "it's okay, she's cheating too"

La el's revenge should be on Sora's father - the man behind it all, fearsome and cruel - yet, he was doing nothing but scold his daughter, get angry, only words but no action - he wasn't doing anything, not investigating, no schemes- nothing at all.
I really don't get why the focus was getting chairman, as if getting the chairman's love will make the villain's poor.

Now if there will be a plot twist where chairman may be the one behind it all and the real culprit that will be interesting, however it still doesn't change the fact that the story has lots of ridiculous plot holes.

The casts did a great job acting..the cinematography is great and honestly speaking, Seo Yeji is carrying this drama. Her acting is what's saving this series, her acting is like a cover up for the messy plot.

Edited: I changed my ratings again, from 8 to 5 and dropped it to 3 after the last episode. I cannot believe how this series turns out. It started really strong but dragged in the middle and ended up really disappointing. I really don't understand why the write pushed that love story between La El and the chairman... when it doesn't even make sense and they have zero chemistry. I don't really expect La el to end up with anyone. I am starting to wonder if things would've been different if they casted a different actor for the role of chairman.

I hated that the long planned revenge just ended up like that... it's as if the writers tried to make the story (and La El) into this smart avenger but doesn't know how. It's really such a waste...
