I was really watching for both!! Joo Won is amazing for sure, but shunji's character under less capable actor would have made the show half as good as it is now!! I think Park Ki Woong stole the show just as much ;)
They totally gave me the feeling of "Kira vs L" (from deathnote anime :P) so thats really something ;)

Well his "friendly" character was soo boring that it didn't interest me at all, but his slow turn to the dark side was soo heart breaking and scary!! At that point I think the actor did such a terrific job!!!

You forgot to mention Shunji's character!!! You're right about the Lead (KangTo) he was AMAZING. But this second lead (Shunji) was JUST AS AMAZING!! Loved their Running after each other outsmarting each other!! For once, both evil & good are smart!! which makes it so much fun!!!
The lead actress & character (Rie) was just as interesting.. only wish she had more screen time :( (I only got to episode 24 till now and got to the point of afraid of watching what has happened BUT also GOTTA SEE IT since its the ONLY thing I THINK ABOUT ALL THE TIME!!!)
For me Oh Mok Dan is a "necessary" boring character :P but the actress didn't do such a great job either... I was actually more excited about the growing relationship between her dad the lead (father figure) But I love what her character does to the rest of the lead especially shunji when he wants to possess her, and Rie when u feel her envy

My first dramas were "when spring comes" and "Hello my Lady" both of which aren't famous or anything, but there were on the KBS World channel that me and my family "accidentally" got when we got the arabic satellite. Then when I missed a last episode of some drama, I started looking it up on the internet.. Thats when I got introduced to also Japanese & Taiwanese dramas :D I gave up Taiwanese after a while but come back to it sometimes, then I switch back and forth between Korean and Japanese ones (Among other things I watch Anime + British + Arabic + American/Canadian) depending on my mood. Gotta say it kinda changed my life :P (I see it in a good way others see it in a bad way)
Your experience is very similar to mine. When you first get introduced to this world, anything would do for you to get to know that world more, then you become more picky, but enjoying it all the same ;)

I've never watched an asian drama for more than 20 episodes... except "History of the Salaryman" which I felt cheated when it was extended so I never planned to watch this show but I promised a friend I'd try the first episode &... got so addicted that 22 episodes went by without me feeling it :P its both hard to watch and addicting at the same time ;)

This was one of the most amazing movies ever!! Tragic and sad, but captivating! Colourful! I dunno what to say to convince people to watch it!! Its really a movie that will be appreciated by all kinds of viewers

Nope not really but their relationship was never the type that would lead to romance. I still loved its really special
