Perfectly balanced mixture of laughter, romance , peculiar weirdness, diverse characters, good acting skills and timing. Maybe the script was not that great as many say and story not so unique but sufficiently different to others. So even though drama follows some common rom-com elements, it still managed to shine. There wouldn't be so many recommendations across the world if it wouldn't, right? ?

When it comes to the leads, I definately prefer Kim Mi So over Lee Young Joon. His character was great don't get me wrong. Fantastic performance. But! Kim Mi So was way more realistic, current and common. He was a kdrama character all the way ? The further you go in the drama the more you notice that the story is shown from more her point of view than his. The focus went from her work, to her house, from the family to Young Joon. We slowly could see what is actually wrong with secretary Kim ? Mr Lee of course played a big role and there was a nice balance present through out whole serie but she was the centerpiece.
