This drama was a waste of great actors. The only thing that makes the two leads suitable for each other is that both of them are somewhat pathetic characters. Until the end the writer didn't change my mind as there was only too little character development. The second lead was too first lead criteria and the story felt rushed to push him without justification.
The actors are great but writing was bad, If you're looking for a great drama this is not it. However if you're just looking for some entertainment this is just ok.
