This was my very first kdrama and it sucked me deep into the world of Asian drama. The chemisty between the leads was flawless and I liked the supporting characters as well. My favourite character was definitely the hardworking secretary Kim Mi So and I liked her relationship with her family (her two sisters and her father). I also liked the mystery sub-plot although the "leads meeting as kids" cliché definitely isn't my favourite one. Park Min Young has been my favourite actress ever since this drama.
