This series definitely deserves some credit for bringing to light the need for mental health support, and of course Park Shin Hye is as awesome as she is able, given the director.
The problem as is often the case is the Male lead overacting to such a cringe worthy degree. Park Hyung Sik delivers such a hammy whiney and immature performance it is almost impossible to believe any grown woman could be attracted to him unless she was looking for a child, not a boyfriend.
