I binged this in one and a half days. It was a lot of fun. I couldn't think of one thing that was wrong with it. I picked it up because I wanted something to watch something funny and it delivered. The writing of each episode's case is fantastic. The show does not directly teach you a lesson but shows many angles of one incident and makes you really think about what you're watching.
I initially didn't want to watch this because I though the main character would be annoying and that the whole story would be whacky but it's really well packaged and done like a pricey bag without a single thread out of place. I don't find the ending "ordinary" for goodness sake. It's like if bad things don't happen then a story is not realistic. I'm over depressive endings just for the sake of them, no thanks. I can look at real life if I wanted to see reality but this is not unrealistic either. The ending wraps up a lot of things in a satisfactory manner and the acting is VERY good. Park Eun Bin really did well. I could feel the character and not the actress. The entire cast was really good. Anyway, this is good. You should watch it!
