What's Wrong With Secreatary Kim was an enjoyable experience for me. Both times. It was the second K-Drama that I watched (after Strangers from Hell) so a lot of the tropes that the series does run through (unfixed childhood trauma, cutesy office romances, knowing each other from childhood, etc bleh) didn't register to me yet. But on re-watch, it still doesn't bother me as much, although a few of those tropes are the weakest aspects of the series. I think this was still a funny drama that captured esseance of what this was going for perfectly. Our male lead, Lee Young Joon, is an arrogant prick (pardon my swearing) but he's likable despite that. It's endearing and you can't help but smile as he looks at himself in the mirror. And I think things like that sum up this show's tone - a lot of it is played for chuckles and light hearted emotions. Kim Mi So is the opposite to Lee Young Joon as she isn't as affluent, more humble and nicer. I personally don't buy that she is dirt poor but that's a nit-pick. Together they are a great pair of leads for us to follow with some great chemistry. They were funny together, especially when Young Joon was feeling jealous or angry, both acted well enough individually, etc.

Where the show lacked was the plot with Young Joon's brother and the confusion between the two. It's not explained well at all. None of it. We don't really know why LYJ's name was changed (it's evident that it was done for a surprise that wasn't a surprise). The Sung Yeon character was just poorly written from start to finish. It's awful. It's a real black mark on what is otherwise a good drama. The supporting plots were all good and added something to the series. It added some depth to our main leads seeing how they are intergrated together. It did make the series feel more than the Mi Soo and Young Joon show. Ji Ah and Gwi Nam's relationship was just the sideplot that makes up for the aforementioned Brother/Mistaken Idendity story.

Park Seo Joon stole the show with a great performance. He brought the Lee Young Joon character to absolute life. Never had a bad scene despite the writing or the plot. He made what could've been a dispiasble character into a ML that everyone loves. Quotes galore, facial expressions galore. He was brilliant. And he matched with PMY perfectly. We all know that Park Min Young isn't the deepest actress (although she is great in When The Whether Is Fine in a darkest, more subtle role that she usually has) but she was really good as well.
