If a drama is on the first page of MDL top shows, it must be somehow worth your time.
I passed this drama in 2017 because I do not know the actors and it is a prison story. Now I have some time and was looking for a worthwhile drama to watch and decided to watch it. I am really glad that I did because this is the kind of drama that stays with you for another 2 days after watching it. All the characters came alive as if you were with them throughout the journey and after the drama ended it was hard to let them go.
