The drama started well, but after the halfway stage, it always left you wanting more.
There was practically no proper character development in this drama which is quite surprising as a viewer.

And the writer tried to hide this by shelving some scenes from the past, back and forth to the present, using tragedy tag as a way to engage emotion which was feint.

The acting was phenomenal, and the casting was outstanding but something felt missing.

The 2nd couple felt wasted.
The 2nd MC was mostly a robot.
The always I'm a good person thing of his irritated me the most.

I would go on and say the writer lost the plot, the actors and the director filled it.
This drama relied on side characters more than it should've.

I can bet if they rewrite this script, it will do better than what it did this time.
The potential was immense.

The romance was left out too long to be explored.
Overall it's decent to watch.
Just grab your popcorn tub, binge it and sleep.
Just the right kind if that's what you're looking for.
