I'm partial to this version of Mischievous Kiss, because it has much more levels to it. The actors portray the characters in a very realistic way, and they were very three dimensional, with emotions that you could actually feel with them as you watched the show. The supporting characters are amazing, and they bring the show to another level.
Its comedic, romantic, and dramatic all at the same time. And you could really understand where each of the characters were coming from, and sympathize with both of them, allowing for a less frustrating, more pleasurable experience.
