At first the premise is good. Until the 5th episode the plot is consistent, fast, interesting, but then it’s predictable, well part of it because what the heck was that subplot in the last episode????? Ridiculous. the whole thing came out of nowhere, so it was a tedious big parentheses in the whole story that didn’t do anything for the plot. I get angry just remembering that.
On the other hand, I’m not going to deny that the chemistry between the protagonists is sublime, and the OST is lovely.
Overall it was fun to watch till 11 episode, but for me the ending is really important when liking and rating a drama, in this case the last episode ruined everything.
