Park Hye Su performance was bad. I really didn't like her. The rest of the actors were good especially Han Chae A.
The main female character was most annoying thing i have seen in a movie for the last 3 years.

The topics that are unusual for dramas, appear in this one. Self-harming, social phobia, suicide, trans-sexuality and est are heavy and difficult to present. By my opinion the way they are shown in  Introvert Boss was a little weak.

There were some really cute and funny moments, so i recommend it i if you want to loose some time and laugh.
