The whole series tries to make the protagonist look like a vulnerable and great guy. But The big problem is that he destroyed another guy's marriage by accident. He hides this fact from all the people who are affected by the marriage being called of. It is a torture to watch the episodes where they are trying to build romance between the protagonist and the girl whose marriage he destroyed. When I looked at the rating for this series it made me really sad. Wow, so many really enjoyed watching a screwed up plot. In addition to the ridiculous screwed up plot, the show also gives the protagonist a psychic ability to see future. This is so random and useless. The three star is because there are aspects like the Oh's (girl) relationship with her parents that is cute.
