The first trailer is out for the new Korean drama watching starring Han Suk Kyu (Romantic Doctor Teacher Kim), Seo Kang Joon (Are You Human Too?), and Kim Hyun Joo (Miracle That We Met). The tension starts to build as we see Kan Suk Kyu listening to a recording and then walking up to a mirror as we see someone looking in from the other side.
Watcher is a thriller about three people (Han Suk Kyu, Seo Kang Joon, Kim Hyun Joo) whose lives were ruined after an accident that team up to bring to light corruption by the police and other powerful people.
Watcher is scheduled to premiere in July on OCN.
