I've just finishes watching this drama today . In my opinion, the first half was pretty good while the second half was really dragged. The premise of the story was great. The first few episodes were funny, interesting, mysterious, everything. After these, the next ones were kind of boring, I may say. The acting was great, again. Each character played the role so good and transmitted a lot of things. The OST sang by Suran was amazing and it is honestly a beautiful song. Would I rewatch it ? Persoanlly, no. But, as you know, people opinions varies so maybe you should give it a try.
