this drama I had doubts I would stay with for 20 episodes but in the end I completed in binge session of last 3 episodes. I think it started out better、 then too much unconvincing romance from around episode 8 [do people really turn 180 degrees round in love-hate relationship?] spoilt it for me but more tension and plot turns and surprises toward end kept me hooked. I do think the romance element was really very weak spot in this drama and truly interfered with the drama but luckily the drama improved and in last episodes I was hooked to see what happened next. as it turned out the drama in the final ending was not for me as good as expected, although the final twist was very original and surprising. I have my own individualistic interpretation about the last two episodes and romance ending which others may not agree with but for me is as convincing as what we are maybe expected to feel 〜that is Park Ji Sang's true love was Joo Hyun Wooー there are hints all over the earlier episodes.ーso when Hyun Woo died in episode 19 Ji Sang was emotionally dead and more accepting of his own sacrifice because his true love was gone. I never found the relationship between Ji Sang and Ri Ta convincing and still less the one created from thin air between Hyun Woo and Soo Eun. I am not saying there was no feeling between him and Ri Ta, just that it was not as deep as for Hyun Woo. the only reason this was not spelled out in my opinion was because they wanted the show to conform to the conventional boy-girl romance、 the last romantic scene between Ji Sang and Ri Ta was emotional bit for me seems very artificial and conventional〜but maybe this is just my fantasy。 also what was the last part all about? total fantasy ?Ri Ta meet an unknown brother or clone of Ji Sang in Kochenia? or had she died and met him in the afterlife? just a continuation of the unconvincing romance to give sort of happy ending I feel。 but in all a very enjoyable drama with excellent start and sufficient interest to stick with to the end 。
