I will considered it as my First K-Drama I have watched many past 2 Years ago before I entered Thai Lakorn and I totally forgot about them except for My Golden Life. Anyways here is My Unpopular Opinion about this Drama that is full of Spoiler so Read it only if you already watched this Drama.

1.) The Story is a pure mess and then it hit with a totally messed Plot Twist. I didn't expect the Amnesia thing but it can't make the Drama better. I want this Drama to be more shorter cause it was very draggy on the Middle.

2.) I don't like the Character Development cause they're getting worse every Episodes. And I don't like any from the Character literally no one is likeable.This could have been great if they make the SFL jealous and it will also help the Romance to make it better

3.) The Acting can't literally save the Whole Drama. It was so great especially SJK but would like it more if the ML Character was strong enough.
As it is Melodrama the Music wasn't something special It was pretty average.
I won't rewatch the Whole Drama but maybe the Hot Kissing Scenes between the Main Leads

Overall this Drama doesn't have satisfying Revenge it has very weak Vengeance actually. That's kinda disappointing cause I watched it because of that tags.

I didn't expect it to be heavy and I feel like it was more heavier than a Lakorn.
