The story is supposed to be funny with romance and maybe a little bit of drama. I can see where they tried, but the whole premise is off. The romance is fine, I actually think they had decent chemistry but if you watch it more than once, it will be more and more difficult to get into the fun of it. The side characters and romances were fun and some people said they were more interesting than the main pairing, but I have to disagree. I think they added to the show, but they weren't so interesting that they stole it. The main couple: Secretary Kim and Narassistic Boss don't have much character arc, considering the content of the show, but it was still very interesting and I enjoyed watching the entire series once. The music was good, but not outstanding. The acting was also good and I thought very in character. To understand why the underlying story behind the main couple, you have to hear some spoilers, but without spoilers, I can say it wasn't well done and was so nonsensical as to have been ridiculous. I would watch it once, but not twice because those moments of understanding will annoy you more if you rewatch.

With spoilers: the main couple have a history. This explains why a totally arrogant and impatient boss would pick a secretary who wasn't fluent in English and experienced enough in the field. She needed to work super hard to catch up to his needs. Over time as they work together, he grows used to how amazing she is and when he thinks of his life without her, he doesn't want her to quit. He tries mulitiple ways to get her to stay and eventually realizes that he loves her. Naturally, he has to overcome his gigantic ego to get to that point, but still. The process is funny and entertaining. She begins to fall in love with him as she sees his emotional sides. Naturally, the catalyst needed to make them both realize how they feel is the return of the boss's self-centered brother who decides that he wants Secretary Kim. Either because he's so arrogant as to think he can have anyone or because he wants to take her from his brother -- he causes problems between them just as they are getting closer.

The actual spoiler is why the premise is really messed up and nonsensical. You see, way back when Secretary Kim was 4-5 years old and her boss was 9-10 and self-centered brother was maybe 11-12, the brother bullies the young boy boss and eventually leaves him in a deserted street where he is kidnapped. Then baby girl Mi So (Secretary Kim) is also kidnapped. They help each other through the experience and end up home safe and sound but naturally with fears. Why Mi So's family doesn't tell her the truth when she asks if she was ever kidnapped makes absolutely no sense to me. Until you recognize and accept that you've been hurt you will never be able to deal with it on an emotional level. So keeping it from her is like telling her to pretend she doesn't feel the pain rather than taking her to the doctor. The young boss hires her because he remembers her, but she doesn't remember and he also doesn't explain. No reason, but that's more excusable. Last, boss's mom and dad who are supposed to be good, normal, loving parents, are actually full time idiots with hateful and stupid notions about family. When older brother feels bad for what he did, he has a mental break and decides that he was the one who was kidnapped. Then mom and dad decide that it's better to pretend that their arrogant, self-centered older son was actually kidnapped than to make him face his wrongdoing. Which is to say that young boss who was the one who was wronged, has to deal with an insufferable prick brother who treats boss as though he were the one in the wrong. Why would the parents take the side of the bully child over the one who has an actual trauma that needs to be dealt with? Because they are stupid, thoughtless, self-centered, and hateful bullies themselves. I mean, they did raise two sons who think they are perfect and hate each other. Who comes up with these plots? If you're going to make them thoughtless bullies, don't have the main character pretend with them. He was an adult, he should have told them the truth and said that their behavior was stupid and hurtful and then told them they needed to tell the truth and stop pandering to their favorite child (obviously the self-centered brother). I will never understand why people who are supposed to be smart and strong and well mannered never can seem to stand up for themselves or say no when something is wrong. Then again, if they were all people who had backbone and common sense and courage, the show would have been over in 3 episodes. Still, that's why I can't watch it twice. I want to ring the mother's neck and kick the older brother very hard in his self-centered face. I get too angry and annoyed at their behavior to be able to watch it twice, but that's me.

Ok, rant over. If you can deal with this amount of stupidity for the background story, the rest is really wonderful. I think they had great chemisty. I thought it was super funny and well acted. I enjoyed it so much that I was tempted to watch it twice (then I tried and had to go bake for 2 hours to get rid of my frustration).
