It's n't d 1st time Iam watching a 16 hrs drama in single stretch ,"Kim soo Hyun" I was his fan girl frm a long time before and waited for his back ,the drama shows the pain of human life ,and it provide a lot of courage and hope for those who struggles to come over frm there past life . It's a complete wroth of time and money , just enjoy the series with a hot cup of coffee☕ saranghe🥰
