To start I really wanted to watch something that I can binge on and Kim Nam Gil is in it, that was the plan when I was going into it. The first ten or so episodes were quite an easy watch thanks to the humour and easy-peasy story line full of romantic cliches: hate to love, love at first sight, the unreachable happy ending -feeling, humoresque episodes between the leads plus there was the time travel aspect to give more fun to it. It does not felt heavy at all even the dramatic parts were low key presented.
Then it became boring and I started to skip more and more mainly because the leads romance bloomed and it was cringeworthy and over-the-top mostly. The villain was quite pathetic, did not added anything to the whole show and I became disinterested in how it will end. The annoying tone of the male lead was particularly disturbing to me. At the end it failed to keep up with the first part of the series. The music was goodish.
To sum up I was glad that I even reached the end and had gotten over it. Not on my recommendations list.
