I was honestly scared to watch this show. Many people were saying how good it is and I didn't want to have too big expectations. I love Park Minyoung's acting and i definitely wasn't surprised how good she was in this show. I was really invested into the story line and was hoping for every pair to get together at the end.
Only thing that made me mad/sad or perhaps not happy was the fact that Yooshik get together with his ex-wife, man deserves better.
(i have to write at least 500 words so lets make it longer i guess)
I want to say, if you're not sure about watching it, just give it a try. Worst thing that can happen it's that you won't like it, but we should try everything. One drama won't kill you.
