My favorite tv show from year 2017. If a tv show can manage me to stay hooked on the whole tv show online, that's really impressive. It's probably the most known Drama tv show and it's really entertaining. You just have to watch While You Were Sleeping. Oh Choong-Hwan's work is very characteristic. He is a director who creates a climate in his productions, which is his trademark. I hope you're excited, so start watching it now!.
