To be honest, These stories individually are not much. We have heard these kind of stories countless times or even better stories altogether.
But what makes this Drama worth your time is it's storytelling. The way the characters are presented and their tales are told is very unique to say the least, nobody has done it like this ever.
Cinematography should be praised as well. All the shots edited together feels more like a book that a drama. It's like I am imagining the story while reading the book and surprisingly the shots exactly matches our imagination.
Screenplay is commendabe. Every shot is Shot to perfection. I would recommend watching the drama in higher pixel value to experience the full adventure.
To say the least, this drama is worth your time and It has the ability to stay in your mind for a long time.
