The best thing about Introverted Boss is the middle part. That and the leading actor. The story is about a boss, whom all call a monster who hides from everyone. However, the truth is that he is just introverted and extremely shy, to the point that he can't speak up for himself. So, the girl was simply annoying at the first episodes, always sticking her nose where she shouldn't and creating trouble. Plus, everyone in the drama treated the shy boss like he was a criminal. Basically, the drama bullied it's lead male till he had hit rock bottom. Things picked up when the script changed and we got a better idea about the mystery regarding the death of the secretary. Plus, the relations in the office got better, as the guy started interacting more with his team, and the later started to understand him. And even though the girl's character was improved, the second male lead got seriously unlikable. Unfortunately, the last two episodes were seriously boring, as the mystery was unveiled and the story had nothing more to say. Finally, one of the pros of this drama was that it gave out the vibe of the "Another miss Oh" drama. So, 3.5 out of 10.
