This drama is a perfect example of what a perfect start but terrible writing can do.
They made it a game of depression.
People aren't that lost after all.
A single word to describe this drama is the ' Titanic '
Starts gracefully and then crashes. Crumbling down all the love it received. --_--
The writing in the last two episodes is so terrible that the drama lost its meaning.

The writer seemed lost somewhere.
To me a drama's first and foremost priority is the plot, everything else comes after.
When your plot does down the hill, it doesn't matter how good the actors are or how good the direction and cinematography have been if the plot turns ridiculous.

Anybody giving this above 7 doesn't understand the difference.
These days I see a lot of people giving high scores to every drama irrespective of what it gave you.

Only watch this if you want to see a form of depression. I had so many expectations from this and I'm hugely disappointed.
