first of all, i don't understand why other people find a lot of loophole in this kdrama when i thought that it was very good. i found myself laughing whenever ma wang and oh gong banter. Their bromance is exceptional!. all the characters portrayed their role in a brilliant way. It may not be considered as a perfect drama but if you will just look on a way how it was crafted, i can say that all the elements of the drama had been put there. The giggles whenever oH gong and sam jang expresses their love to each is beyond compare. the manly gesture of Oh Gong is something you can look forward to. The humor,friendship and family relationship is one of the highlights of this drama. There is an open ending. but it was properly explained . second book is a must
