Well if you have heard of "Dangerous Liaisons" (or as the original "Les liaisons dangereuses" novel by Choderlos de Laclo who inspired a chain of movie adaptations) this story is all to familiar. The only difference is that the Korean version of this story makes the viewer root for the main characters, who become almost likeable and beautiful. I never thought I'd cry for Valmont (Korean version, of course). Thinking about it, it's much easier to get attached to Bae Yong Joon than you can ever do to John Malkovich!
