Set in modern day Korea, This Isn't Romance opens with the first meeting between the estranged siblings after their separation as children.Miso, driven by guilt over the abandonment, returns to Korea to seek out Han and make amends for the past but in doing so rekindles the dangerous passions within their relationship.What ensues is a provocative and controversial drama incorporating themes of violence, tempestuous incest and self-brutality.
