This is first time I am reviewing a kdrama. I would rather say this series is so great that I wanted to make recommendation. I loved the way series started, how much strong characters were portrayed, female lead was simply amazing. I first saw her in _Goblin_ and I wasn't amazed there as much as I am after this series. Talking about Lee min ho, I can't express him in one word. Min ho have always played rich characters and honestly speaking he makes people wonder his beauty. He really played the role very well and the ongoing chemistry was amazing. There is one scene where he cried and that moment my eyes also welled up with tears. I felt amazing watching this series. And not to skip the series stealer Wo do hwan, I had watched his series _Tempted_ and in my opinion he is really underrated. If he is given with an opportunity he can make fortune out of it. The best part of the series was it's ending. Normally any kdrama which is made with something super power or kind not acceptable plot like time machine , it mostly ends illogically but not with this series. The writer have tried to make good detailing although there are loopholes but it's one of my top 3 best series I ever watched till now..
