The major changes of the plot from the original made this series adaptation generic and predictable. The origins of Jae-Eon's personality had so much depth and interesting compare to the series version. It brought psychological aspect and reasonable pattern to Jae-Eon's manipulative behavior. Whereas the adaptation only turned him into a shallow and plain character with no direction. This was just a typical plot of a geek girl change the bad boy's life to 180°. Not worth to watch.
