a slice of life office drama with great cast

i was so curious why this show's rating was sooo low. with this cast, how could it go wrong? i guess its a typical office drama with generic writing. not everyone would appreciate its low pacing... especially if you have seen miseang. one would not take a minute to watch this. but not for me. im a big hye ri fan. The drama is also surrounded with familar actors that i love. With gret character developements and likable characters, why am i the only one who was hooked on this drama. the question still bothers me. hehehehe.
